Phase-space excluded-volume approach for light clusters in nuclear medium
Rui Wang🇮🇹 · Zhen Zhang🇨🇳 · Stefano Burrello🇮🇹 · Maria Colonna🇮🇹 · Edoardo G. Lanza🇮🇹
A phase-space excluded-volume approach is developed to investigate the in-medium properties of light clusters in nuclear matter. In this approach, light clusters can exist only if the total nucleon phase-space occupation of the surrounding nuclear medium -- including explicit contributions from light clusters -- is sufficiently low. The distribution functions of nucleons and light clusters are determined self-consistently by accounting for the interplay between in-medium effects and thermodynamic properties. By employing standard Skyrme energy-density functionals to model the nuclear mean-field potential, the approach enables the evaluation of the Mott momentum and the fraction of light clusters in nuclear matter. Furthermore, it can be readily integrated into dynamical models, to study in-medium effects on light clusters, based on measured yields in heavy-ion collisions.

np spin correlations in the deuteron ground state
Ashutosh Singh · Ankit Kumar Das · Ankit Kumar · P. Arumugam
The deuteron is the simplest atomic nucleus made of two particles - a proton and a neutron. In this work, we study how their spins are quantum entangled with each other. We study two cases: when the deuteron is in a fixed projection of total angular momentum, and when it exists in a superposition of all projections. Our findings show that the spins are most entangled when the total projection is zero, and that strong entanglement still exists even when all spin states are superposed.

Chiral Invariant Mass Constraints from HESS J1731 347 in an Extended Parity Doublet Model with Isovector Scalar Meson
Yuk-Kei Kong🇯🇵 · Bikai Gao🇯🇵 · Masayasu Harada🇯🇵
The recent discovery of a central compact object (CCO) within the supernova remnant HESS J1731-347, with mass $0.7 7_{- 0.17}^{+ 0.20} M_{⊙}$ and radius $10. 4_{- 0.78}^{+ 0.86}$ km is the lightest and smallest compact object ever observed. We identify it as an ultra-light Neutron star (NS) and constrain the chiral invariant mass of nucleon $m_{0}$ from the observational data of NS using an extended parity doublet model with including the isovector scalar meson $a_{0} (980)$ . We study the higher order asymmertic matter properties such as the symmetry incompressibility $K_{sy m}$ and the symmetry skewness $Q_{sy m}$ in the presence of $a_{0}$ meson. We find that $K_{sy m}$ and $Q_{sy m}$ is sensitive to the chiral invariant mass of nucleon $m_{0}$ in the presence of $a_{0}$ meson. We show that the equation of state in the present model satisfies all observational constraints within $2 σ$ credible region including the HESS J1731-347 observation, as well as the constraint from $K_{sy m}$ when $740 MeV ≲ m_{0} ≲ 860 MeV$ for $L_{0} =$ 57.7 MeV. Yet, the $1 σ$ constraint from neutron stars appears to be not fully compatible with the constraint from $K_{sy m}$ from the present model.

Photon Emission from Nucleon-Nucleon Bremsstrahlung in Fermi-energy Heavy-Ion Collisions
Thomas Onyango🇺🇸 · Ralf Rapp🇺🇸
The emission of direct (hard and thermal) photons from nucleon-nucleon Bremsstrahlung in heavy-ion collisions at Fermi energies is analyzed. We utilize a photon emission rate based on a quantum-field-theoretical model together with nucleon distribution functions extracted from a coarse-graining method of transport model simulations. The latter accounts for off-equilibrium effects during the early stages of nuclear collisions primarily occurring in the beam direction while the transverse-momentum distributions are amenable to a thermal description. With this setup, we quantify the contributions from first-chance nucleon-nucleon collisions and the subsequent transition to a thermal source to the photon energy spectrum measured from Ca-Ca collisions at 35 A $\cdot$ MeV bombarding energy. We find that most of the hard photons are produced in the initial stages of heavy-ion collisions from primordial collisions where nucleons move with the initial collective nuclear motion while the emission from the later stages plays a sub-dominant role. We compare our calculations to experimental measurements of a differential photon-energy spectrum from a collision system of similar size and beam energy, thereby including acceptance cuts as applied in the detectors.

Impact of $Ξ$ -Hypernuclear Constraints on Relativistic Equation of State and Properties of Hyperon Stars
Shi Yuan Ding🇨🇳 · Xiang Dong Sun🇨🇳 · Bao Yuan Sun🇨🇳 · Ang Li🇨🇳
Significant uncertainties persist in describing the equation of state and internal structure of hyperon stars due to the limited understanding of the mechanisms underlying hyperon interactions. Constraining the interaction parameter space through a combination of the latest astronomical observations and hypernuclear physics experiments is therefore essential. In this study, we incorporate experimental constraints from $Ξ$ hypernuclear physics on top of $Λ$ hyperons considered in \citet{Sun2023APJ942.55}. Specifically, based on updated measurements of hyperon separation energies from $Ξ$ hypernuclear experiments, sets of $Ξ N$ effective interactions are constructed and a linear correlation between their scalar ( $σ$ ) and vector ( $ω$ ) coupling strength ratios is proposed as a constraint derived from $Ξ$ hypernuclear physics. Together with experimental correlations and astronomical observational data, four types of analyses are performed to constrain hyperon-nucleon interactions and the properties of hyperon stars. Compared to the vector $ω$ meson-hyperon coupling, the introduction of linear correlations in hypernuclear physics imposes a more substantial constraint on the scalar $σ$ meson-hyperon coupling, significantly enhancing its coupling strength and thereby ensuring the stiffness of the equation of state, highlighting the crucial role of hypernuclear studies in solving the hyperon puzzle problem. Consequently, a maximum mass of around $2 M_{⊙}$ can be achieved with all five interactions considered in this study under the combined constraints from astronomical observations and nuclear physics. With more reliably estimated hyperon-nucleon contributions, the uncertainties in both the fractions and the threshold densities at which hyperons appear inside neutron stars are notably reduced, along with those in the mass-radius predictions.

Impact of pion tensor force on alpha clustering in $^{20}$ Ne
Zhao Jing Chen · Bao Yuan Sun
The nuclear clustering, as a quantum phase transition phenomenon governed by strong interactions, exhibits characteristics that are highly sensitive to the specific features of nuclear forces. Here, we examine how nuclear deformation and tensor forces influence $α$ -cluster formation in light nuclei. The axially deformed relativistic Hartree-Fock-Bogoliubov model is utilized to investigate the clustering structure of the $^{20}$ Ne nucleus, at both the ground state and the excited state with a superdeformed prolate. The nuclear binding energies and the canonical single particle levels are obtained at different quadruple deformation, and the role of tensor force embedded in the Fock diagram of $π$ -pseudovector ( $π$ -PV) coupling is revealed. It is shown that the level branches from the degenerated spherical orbits at the deformed prolate case are enlarged due to the extra contribution from pion-exchanged tensor force. Correspondingly, the excitation energy in this superdeformed prolate state is reduced due to the noncentral tensor interaction, leading to a predicted value which is much closer to the referred threshold for the $2 α$ decay mode of $^{20}$ Ne. Possible $α$ -clustering configurations in $^{20}$ Ne are then characterized by examining the nucleonic localization function. Although the contribution to the ground state is relatively small, the density profile and nucleonic localization are significantly changed by the pion tensor force for the superdeformed prolate excited state, as further evidenced by characterising the level mixing in the spherical basis components. The results reveal the extra role of the tensor force, correlated to the evolved single-particle levels with nuclear deformation, in the formation and stability of nuclear clustering.

Simulation studies of the isovector reorientation effect of deuteron scattering on heavy target
Baiting Tian · Boyuan Zhang · Dawei Si · Sheng Xiao · Yijie Wang · Tadaaki Isobe · Hideaki Otsu · Li Ou · Zhigang Xiao
The isovector reorientation (IVR) effect of deuteron scattering on heavy target provides a novel means to probe the nuclear isovector potential, which gives rise to the nuclear symmetry energy. The simulation studies on the experimental measurement of IVR effect using the SAMURAI terminal at RIKEN Nishina center have been performed to demonstrate the feasibility of the experiment. By introducing a well-designed polarimeter to detect the $p (d, d) p$ elastic scattering, monitoring of the tensor polarization of the deuteron beam can be implemented. The protons and neutrons produced by the breakup of polarized deuterons scattering off heavy targets are designed to be measured by proton drift chamber (PDC) combined with the SAMURAI magnet and NEBULA detector, respectively. The detector responses are simulated using Geant4 framework, where the events of the deuteron elastic breakup are generated by an Improved Quantum Molecular Dynamics model. The results of reconstructing the deuteron breakup events demonstrate the feasibility of detecting the IVR effect at SAMURAI with both longitudinal and transverse tensor polarized deuteron beams with a polarization degree of approximately 80\%.

Bound Deuteron-Antideuteron System (Deuteronium): Leading Radiative and Internal-Structure Corrections to Bound-State Energies
G. S. Adkins🇺🇸 · U. D. Jentschura🇺🇸
We evaluate the energy levels of the deuteronium bound system, which consists of a deuteron and an antideuteron, with a special emphasis on states with nonvanishing orbital angular momenta. The excited atomic bound states of deuteronium constitute probes for the understanding of higher-order quantum electrodynamic corrections for spin-1 particles in a bound system where the typical field strength of the binding Coulomb field (at a distance of the generalized Bohr radius) exceeds Schwinger's critical field strength. For states with nonvanishing angular momenta, effects due to the internal structure of the deuteron and virtual annihilation contributions are highly suppressed. Relevant transitions are found to be in a frequency range accessible by standard laser spectroscopic techniques. We evaluate the leading and next-to-leading energy corrections of orders alpha^3 m_d and alpha^4 m_d , where alpha is the fine-structure constant and m_d is the deuteron mass, and also investigate internal-structure corrections: hadronic vacuum polarization, finite-size effects, and strong-interaction corrections.

Direct Inference of Nuclear Equation-of-State Parameters from Gravitational-Wave Observations
Brendan T. Reed🇺🇸 · Cassandra L. Armstrong🇺🇸 · Rahul Somasundaram🇺🇸 · Duncan A. Brown🇺🇸 · Collin Capano🇺🇸 · Soumi De🇺🇸 · Ingo Tews🇺🇸
The observation of neutron star mergers with gravitational waves (GWs) has provided a new method to constrain the dense-matter equation of state (EOS) and to better understand its nuclear physics. However, inferring nuclear microphysics from GW observations necessitates the sampling of EOS model parameters that serve as input for each EOS used during the GW data analysis. The sampling of the EOS parameters requires solving the Tolman-Oppenheimer-Volkoff (TOV) equations a large number of times -- a process that slows down each likelihood evaluation in the analysis on the order of a few seconds. Here, we employ emulators for the TOV equations built using multilayer perceptron neural networks to enable direct inference of nuclear EOS parameters from GW strain data. Our emulators allow us to rapidly solve the TOV equations, taking in EOS parameters and outputting the associated tidal deformability of a neutron star in only a few tens of milliseconds. We implement these emulators in \texttt{PyCBC} to directly infer the EOS parameters using the event GW170817, providing posteriors on these parameters informed solely by GWs. We benchmark these runs against analyses performed using the full TOV solver and find that the emulators achieve speed ups of nearly \emph{two orders of magnitude}, with negligible differences in the recovered posteriors. Additionally, we constrain the slope and curvature of the symmetry energy at the 90\% upper credible interval to be $L_{sym} ≲ 106$ MeV and $K_{sym} ≲ 26$ MeV.

Extraction of jet-medium interaction details through jet substructure for inclusive and gamma-tagged jets
Y. Tachibana · C. Sirimanna · A. Majumder · A. Angerami · R. Arora · S. A. Bass · Y. Chen · R. Datta · L. Du · R. Ehlers · H. Elfner · R. J. Fries and 40 other authors
We present a comprehensive study of jet substructure modifications in high-energy heavy-ion collisions using both inclusive jets and $γ$ -tagged jets, based on a multi-stage jet evolution model within the Monte Carlo framework JETSCAPE. To investigate hard parton splittings inside jets, we focus on Soft Drop observables. Our results for the groomed splitting radius and groomed jet mass distributions of inclusive jets show a slight narrowing compared to proton-proton baselines. We demonstrate that this apparent narrowing is primarily a selection bias from energy loss, rather than a direct modification of the splitting structure, by analyzing $γ$ -tagged jets, where such bias is eliminated or significantly reduced. We also show that quark jets exhibit genuine modifications in their splitting structure, which is not seen in gluon jets. These effects are clearly visible in the substructure of $γ$ -tagged jets, which are dominated by quark jets, but are not apparent for inclusive jets. This demonstrates that $γ$ -tagged jets offer a powerful probe of medium-induced modifications to the hard splitting structure of jets.

Pion Valence Structure at Intermediate x in the Residual Field Approach
Joseph Maerovitz🇺🇸 · Christopher Leon🇺🇸 · Misak Sargsian🇺🇸
We calculate the valence parton distribution function~(PDF) of pion, within the theoretical approach based on spectral function representation of valence quarks in the pion. In this approach we assume that the soft partonic structure of pion is defined by the valence $q q ˉ$ cluster, consisting of current quarks, embedded in the residual field of the pion. The valence PDF is calculated using phenomenological Light-Front wave functions for the $q q ˉ$ cluster and the residual field. Our result indicates that the peak position of the x weighted valence PDF~(xPDF) depends on parameters characterizing the virtuality of the cluster and the mass of the residual system. Magnitudes of these parameters are obtained by fitting to the height and the peak position of empirical pion xPDF evaluated at starting $Q_{0}$ . They indicate that unlike the nucleon case, very little residual mass is needed to describe existing pion PDFs at intermediate x. They also indicate that the $q q ˉ$ -cluster is highly virtual and on average the interacting quark carries almost all of the momentum of the $q q ˉ$ cluster. This picture is consistent with the dominance of the Feynman mechanism leaving little room for the hard component in the PDF, and practically describing $\sim (1 - x)$ behavior observed recently at $x \to 1$ limit. Our non-trivial observation is that the height and the peak position of xPDF define the analytic behavior of valence PDF at $x \to 1$ limit.

Bayesian Analysis and Analytic Continuation of Scattering Amplitudes from Lattice QCD
Miguel Salg🇨🇭 · Fernando Romero-López🇨🇭 · William I. Jay🇺🇸
We present a novel procedure for analyzing the lattice-QCD spectrum via the finite-volume formalism to obtain constraints on multi-hadron scattering amplitudes at both real and complex energies. This approach combines a Bayesian reconstruction of the scattering amplitude on the real axis with Nevanlinna interpolation for analytic continuation to complex-valued energies. The method is non-parametric, inherently accounting for parametrization dependence within the uncertainty. We demonstrate the applicability of this approach using both toy data and real lattice-QCD data in resonant systems from the HadSpec and BaSc collaborations.

The Carrollian Kaleidoscope
Arjun Bagchi🇮🇳 · Aritra Banerjee🇮🇳 · Prateksh Dhivakar🇨🇦 · Saikat Mondal🇮🇳 · Ashish Shukla🇮🇳
The Carroll group arises in the vanishing speed of light limit of the Poincaré group and was initially discarded as just a mathematical curiosity. However, recent developments have proved otherwise. Carroll and conformal Carroll symmetries are now ubiquitous, appearing in diverse physical phenomena starting from condensed matter physics to quantum gravity. This review aims to provide the reader a gateway into this fast-developing field. After an introduction and setting the stage with basics of the symmetry in question, we detail the construction of Carrollian and Carrollian Conformal field theories (CCFT). We then focus on applications. By far the most popular of these applications is in the context of the construction of holography in asymptotically flat spacetimes (AFS) in terms of a co-dimension one dual CCFT. We review the early work on AFS $_{3}$ /CCFT $_{2}$ before delving into an in-depth analysis for the construction of the dual to 4D AFS. Two other important sets of applications are in hydrodynamics and in condensed matter physics, which we discuss in detail. Carroll hydrodynamics is introduced as the $c \to 0$ limit of relativistic hydrodynamics first and then reconstructed from a symmetry based approach. Relations to ultrarelativistic flows and connections to the quark-gluon plasma are discussed with concrete examples of the Bjorken and Gubser flow models. In condensed matter applications, we cover connections to fractons, flat bands, and phase separation in Luttinger liquid models. To conclude, we give very brief outlines of other topics of interest including string theory and black hole horizons.

Holographic Baryons as Quantum Hall Droplets
Francesco Bigazzi🇮🇹 · Aldo Lorenzo Cotrone🇮🇹 · Andrea Olzi🇮🇹 · Jean-Loup Raymond🇮🇹
We provide a first-principle construction of baryons as quantum Hall droplets in single-flavor holographic QCD. The baryons are described as charged D6-branes with a circular boundary on a flavor D8-brane in the Type IIA backgrounds dual to the confining and non-confining phases. The holographic description allows us to calculate precisely their properties, such as mass and size. We also consider other objects with baryonic charge, such as vortons, domain walls with holes, and "sandwich vortons", and discuss the relative (meta)stability of all these configurations.

Effects of hadronic reinteraction on jet fragmentation from small to large systems
Hendrik Roch🇺🇸 · Aaron Angerami · Ritu Arora · Steffen Bass · Yi Chen · Ritoban Datta · Lipei Du · Raymond Ehlers · Hannah Elfner · Rainer J. Fries · Charles Gale · Yayun He and 40 other authors
We investigate the impact of the hadronic phase on jet quenching in nuclear collider experiments, an open question in heavy-ion physics. Previous studies in a simplified setup suggest that hadronic interactions could have significant effects, but a systematic analysis is needed. Using the X-SCAPE event generator with the SMASH afterburner, we study the role of hadronic rescattering on jet fragmentation hadrons. Applying this framework to $e^{+} + e^{-}$ collisions, we demonstrate that even in small systems with limited particle production, hadronic interactions lead to measurable modifications in final-state hadronic and jet observables by comparing scenarios with and without afterburner rescattering.

Role of nuclear and electromagnetic fragmentation in the charge-changing reactions of 18O on carbon and lead targets at around 370 MeV/nucleon
J.R. Liu · B.-H. Sun · J.W. Zhao · G. Guo · G.S. Li · Z.Z. Li · Y.F. Niu · I. Tanihata · S. Terashima · F. Wang · M. Wang · X.L. Wei and 18 other authors
Charge-changing cross sections (CCCSs) of 18O on carbon (C) and lead (Pb) targets have been measured with an uncertainty of less than 4% at around 370MeV/nucleon. We evaluate the contributions of nucleon-nucleon (NN) and electromagnetic (EM) interactions to CCCSs by considering the direct proton removal process, the charged particle evaporation (CPE) after neutron removal, and the EM excitation. We conclude that the CPE accounts for 12.3% and 5% of CCCSs on C and Pb, respectively. Only less than 1% of CCCSs of 18O is attributed to the EM excitation. Further investigation of projectiles from 18O to 197Au on C, silver (Ag) and Pb targets at 300 and 900MeV/nucleon show that the contribution of EM to CCCSs on Ag and Pb increases with projectile mass numbers and incident energies, and can reach 10% for 197Au on Pb at 900MeV/nucleon. In contrast, the EM contribution to CCCS is negligible for all projectiles on C at both energies.

An unusual type-I X-ray burst from the neutron star X-ray binary IGR J17591-2342: a double-photospheric-radius-expansion burst?
Sudip Bhattacharyya · Akshay Singh · Andrea Sanna
Type-I X-ray bursts observed from neutron stars originate from intermittent unstable thermonuclear burning of accreted matter on these stars. Such bursts, particularly those reaching the Eddington luminosity and having a temporary photospheric radius-expansion due to radiation pressure, provide a testbed to study nuclear fusion processes in intense radiation, gravity, and magnetic fields. Here, we investigate time-resolved spectroscopic properties of a type-I burst from the accretion-powered millisecond X-ray pulsar IGR J17591-2342. Our basic spectral model includes an absorbed blackbody to describe the burst emission and an absorbed power law to represent the non-burst emission. The blackbody normalisation shows two consecutive humps aligned with blackbody temperature dips during the burst. Such an unusual behaviour could imply two consecutive photospheric radius-expansion events during the same burst or a systematic metallicity evolution in the neutron star atmosphere. However, our spectral analysis suggests the latter option is less likely to be happening for IGR J17591-2342. The novel former option implies that sufficient fuel survived after the first photospheric radius-expansion event to power a second similar event a few seconds later, challenging the current theoretical understanding. If confirmed, the double photospheric radius-expansion event observed in IGR J17591-2342 suggests the possibility of avoiding photospheric expansion at luminosities exceeding Eddington. Mechanisms such as temporary enhancement of the magnetic field by convection and confinement of the plasma could be invoked to explain the peculiar behaviour of the source.

Inclusive quasielastic (anti-)neutrino nucleus scattering within the Standard Model and beyond
E. Hernández🇪🇸 · J. Nieves🇪🇸 · J.E. Sobczyk🇸🇪
We derive fully general expressions for the inclusive (anti-)neutrino-induced nuclear quasielastic production of a strange or charmed baryon $Y$ , considering all dimension-six new physics operators relevant to the semileptonic $q \to q^{'} ℓ ν_{ℓ}$ transition with both left- and right-handed neutrino fields. We illustrate the formalism by applying it to the $Λ_{c}$ production in neutrino nucleus scattering. The nuclear response is computed using a state-of-the-art {\it ab initio} spectral function, based on realistic nuclear many-body wavefunctions obtained via coupled-cluster method and a nuclear Hamiltonian derived from chiral effective field theory. We also highlight the role played by the final state interactions between the produced $Y$ hyperon and the residual nuclear system, which can obscure potential new physics signals in this (anti-)neutrino nucleus reaction. Our results improve upon previous studies that neglected nuclear corrections and uncertainties -- effects we show to be comparable to, or even larger than, those expected from new physics.

Parton Distributions on a Quantum Computer
Jiunn-Wei Chen🇹🇼 · Yu-Ting Chen🇹🇼 · Ghanashyam Meher🇹🇼
We perform the first quantum computation of parton distribution function (PDF) with a real quantum device by calculating the PDF of the lightest positronium in the Schwinger model with IBM quantum computers. The calculation uses 10 qubits for staggered fermions at five spatial sites and one ancillary qubit. The most critical and challenging step is to reduce the number of two-qubit gate depths to around 500 so that sensible results start to emerge. The resulting lightcone correlators have excellent agreement with the classical simulator result in central values, although the error is still large. Compared with classical approaches, quantum computation has the advantage of not being limited in the accessible range of parton momentum fraction $x$ due to renormalon ambiguity, and the difficulty of accessing non-valence partons. A PDF calculation with 3+1 dimensional QCD near $x = 0$ or $x = 1$ will be a clear demonstration of the quantum advantage on a problem with great scientific impact.

Line Tension Reshapes Nucleation at Surface Edges: A Generalized Theory for Nanopore Activation
Yanchen Wu · Martin Z. Bazant · Allan S. Myerson · Richard D. Braatz
Heterogeneous nucleation at surface edges is pervasive across nature and industry, yet the role of line tension, arising from asymmetric capillary interactions at geometric singularities, remains poorly understood. Herein we develop a generalized nucleation theory that explicitly incorporates line tension induced by edge pinning, thereby extending classical frameworks to account for nanoscale confinement and interfacial asymmetry. Through analytical treatment of droplet formation within geometrically defined nanopores, we derive a closed-form expression for the edge-pinned line tension as a function of Laplace pressure, pore geometry, and wettability. This formulation reveals that line tension can significantly reshape the nucleation energy landscape, introducing nontrivial dependencies on contact angle and pore morphology. Our results uncover a tunable, geometry-mediated mechanism for controlling nucleation barriers, offering predictive insight into phase transitions in confined environments and suggesting new strategies for design in applications ranging from nanofluidics to crystallization control.
