The Full Lepton Flavor of the Littlest Higgs Model with T-parity
F. del Aguila🇪🇸 · Ll. Ametller🇪🇸 · J.I. Illana🇪🇸 · J. Santiago🇪🇸 · P. Talavera🇪🇸 · R. Vega-Morales🇪🇸
We re-examine lepton flavor violation (LFV) in the Littlest Higgs model with T--parity (LHT) including the full T--odd (non-singlet) lepton and Goldstone sectors. The heavy leptons induce two independent sources of LFV associated with the couplings necessary to give masses to the T--odd mirror fermions and to their partners in right-handed $S O (5)$ multiplets, respectively. The latter, which have been neglected in the past, can be decoupled from gauge mediated processes but not from Higgs mediated ones and must therefore also be included in a general analysis of LFV in the LHT. We also further extend previous analyses by considering on-shell $Z$ and Higgs LFV decays together with the LFV processes at low momentum transfer. We show that current experimental limits can probe the LHT parameter space up to global symmetry breaking scales $f \sim 10$ TeV. For lower $f$ values $≳ 1$ TeV, $μ - e$ transitions require the misalignment between the heavy and the Standard Model charged leptons to be $≲ 1 %$ . Future LFV experiments using intense muon beams should be sensitive to misalignments below the per mille level. For $τ$ LFV transitions, which could potentially be observed at Belle II and the LHC as well as future lepton colliders, we find that generically they can not discriminate between the LHT and supersymmetric models though in some regions of parameter space this may be possible.

Bounds on Neutron- Mirror Neutron Mixing from Pulsar Timings and Gravitational Wave Detections
Itzhak Goldman🇮🇱 · Rabindra N. Mohapatra🇺🇸 · Shmuel Nussinov🇮🇱
The mass loss in putative neutron star to mixed neutron - mirror neutron star transition implies a significant change of orbital period. The precise constancy of the latter can restrict scenarios recently suggested where neutron to mirror neutron mixing occurring in neutron stars, transforms them into mixed stars helping explain the narrow mass distribution observed for pulsars in binary systems. The observation of a very old millisecond pulsar with a mass of 2 solar masses is an additional strong constraint on the above transition.We also note that the observed gravitational waves signals from neutron-neutron stars merger constrain the neutron to mirror neutron transitions inside neutron stars. These considerations exclude a large region in the $ϵ^{'}$ , $δ m^{'}$ plane of the neutron-mirror neutron mixing and mass

Fundamental oscillation modes of scalar bosonic dark stars
C. Vásquez Flores🇧🇷 · Alessandro Parisi🇹🇼 · Chian-Shu Chen🇹🇼 · Germán Lugones🇧🇷
We perform a detailed analysis of the fundamental $f$ -mode frequencies and damping times of nonrotating boson stars in general relativity by solving the nonradial perturbation equations. Two parameters which govern the microscopic properties of the bosonic condensates, namely the self-coupling strength and the mass of scalar particle, are explored. These two quantities characterize oscillations of boson star. Specifically, we reexamine some empirical relations that describe the $f$ -mode parameters in terms of mass and radius of the boson stars. We found it is possible to constrain the equation of state if the fundamental oscillation mode is observed.

Dynamical analysis of the $X$ resonance contributions to the decay $J / ψ \to γ X \to γ ϕϕ$
A.A. Kozhevnikov🇷🇺
The dynamics of the $J^{P C} = 0^{-+}$ , $0^{++}$ , and $2^{++}$ resonance contributions to the decay $J / ψ \to γ X (J^{P C}) \to γ ϕϕ$ is analysed using the data obtained by BESIII collaboration. The effective coupling constants parameterising invariant amplitudes of the transitions $J / ψ \to γ X (J^{P C})$ and $X (J^{P C}) \to ϕϕ$ and masses of $X (J^{P C})$ resonances are found from the fits. They are used for evaluation of the branching fractions $B_{X (J^{P C}) \to ϕϕ}$ , relative branching fractions $B_{J / ψ \to γ X (J^{P C}) \to γ ϕϕ}$ , and for obtaining the photon angular distributions.

Transport coefficients of hadronic matter in a van der Walls hadron resonance gas model
Ranjita K. Mohapatra · Hiranmaya Mishra · Sadhana Dash · Basanta K. Nandi
We estimate the transport coefficients like shear and bulk viscosities of hot hadronic matter in van der Walls hadron resonance gas ( VDW HRG ) model in the relaxation time approximation. We also have compared these results with excluded volume hadron resonance ( EV HRG ) calculations. $η / s$ decreases as the temperature of the hadronic system increases at a fixed baryon chemical potential. $η / s$ in VDW HRG is always less than that of EV HRG case due to the large entropy density in VDW HRG compared to EV HRG case. At a fixed chemical potential, $ζ / s$ in VDW HRG is also less than that of EV HRG case. We also have estimated these transport coefficients along the freezeout curve. There is an increase in chemical freezeout temperature in VDW HRG case determined from the universal condition $E / N = ϵ / n \sim 1$ $G e V$ . We also have calculated the variation of attraction parameter along the freezeout curve $E / N = ϵ / n \sim 1$ $G e V$ keeping the freezeout parameters same as in ideal HRG and the repulsion parameter fixed. We observe a nontrivial variation of attraction parameter along the freezeout curve where it increases in the meson dominated region and decreases in the baryon dominated region along the chemical freezeout curve. $η / s$ in EV HRG is always large than that VDW HRG along the freezeout curve. This is also true for $ζ / s$ .

Symmergent Gravity, Seesawic New Physics, and their Experimental Signatures
Durmus Demir🇹🇷
The standard model of elementary particles (SM) suffers from various problems, such as power-law ultraviolet (UV) sensitivity, exclusion of general relativity (GR), and absence of a dark matter candidate. The LHC experiments, according to which the TeV domain appears to be empty of new particles, started sidelining TeV-scale SUSY and other known cures of the UV sensitivity. In search for a remedy, in this work, it is revealed that affine curvature can emerge in a way restoring gauge symmetries explicitly broken by the UV cutoff. This emergent curvature cures the UV sensitivity and incorporates GR as symmetry-restoring emergent gravity ({\it symmergent gravity}, in brief) if a new physics sector (NP) exists to generate the Planck scale and if SM+NP is fermi-bose balanced. This setup, carrying fingerprints of trans-Planckian SUSY, predicts that gravity is Einstein (no higher-curvature terms), cosmic/gamma rays can originate from heavy NP scalars, and the UV cutoff might take right value to suppress the cosmological constant (alleviating fine-tuning with SUSY). The NP does not have to couple to the SM. In fact, NP-SM coupling can take any value from zero to $Λ_{S M}^{2} / Λ_{N P}^{2}$ if the SM is not to jump from $Λ_{S M} \approx 500 GeV$ to the NP scale $Λ_{N P}$ . The zero coupling, certifying an undetectable NP, agrees with all the collider and dark matter bounds at present. The {\it seesawic} bound $Λ_{S M}^{2} / Λ_{N P}^{2}$ , directly verifiable at colliders, implies that: {\it (i)} dark matter must have a mass $≲ Λ_{S M}$ , {\it (ii)} Higgs-curvature coupling must be $\approx 1.3%$ , {\it (iii)} the SM RGEs must remain nearly as in the SM, and {\it (iv)} right-handed neutrinos must have a mass $≲ 1000 TeV$ . These signatures serve as a concise testbed for symmergence.

$Z_{c} (4430)$ and $Z_{c} (4200)$ as triangle singularities
S. X. Nakamura (Univ. Science and Technology of China)🇧🇷 · K. Tsushima (Univ. Cruzeiro do Sul)🇧🇷
$Z_{c} (4430)$ discovered by the Belle and confirmed by the LHCb in $B ˉ^{0} \to ψ (2 S) K^{-} π^{+}$ is generally considered to be a charged charmonium-like state that includes minimally two quarks and two antiquarks. $Z_{c} (4200)$ found in $B ˉ^{0} \to J / ψ K^{-} π^{+}$ by the Belle is also a good candidate of a charged charmonium-like state. We demonstrate that kinematical singularities in triangle loop diagrams induce a resonance-like behavior that can consistently explain the properties (mass, width, and Argand plot) of $Z_{c} (4430)$ and $Z_{c} (4200)$ from the experimental analyses. The triangle diagrams include only experimentally well-established hadrons. Applying this idea to $Λ_{b}^{0} \to J / ψ p π^{-}$ , we also identify triangle singularities that behave like $Z_{c} (4200)$ , but no triangle diagram is available for $Z_{c} (4430)$ . This is consistent with the LHCb's finding that their description of the $Λ_{b}^{0} \to J / ψ p π^{-}$ data is significantly improved by including a $Z_{c} (4200)$ contribution while $Z_{c} (4430)$ seems to hardly contribute. Even though the proposed mechanisms have uncertainty in the absolute strengths which are currently difficult to estimate, they are certainly a compelling alternative to tetraquark-based interpretations of $Z_{c} (4430)$ and $Z_{c} (4200)$ .

Fate of the doubly heavy spin $- 3/2$ baryons in a dense medium
N. Er🇹🇷 · K. Azizi🇹🇷
We investigate the behavior of the doubly heavy spin $- 3/2$ baryons in cold nuclear matter. In particular, we study the variations of the spectroscopic parameters of the ground state $Ξ_{Q Q^{'}}^{*}$ and $Ω_{Q Q^{'}}^{*}$ particles, with $Q$ and $Q^{'}$ being $b$ or $c$ quark, with respect to the changes in the density of the nuclear medium. We find the shifts on the parameters under question at saturation medium density compared to their vacuum values. It is observed that the parameters of the $Ξ_{Q Q^{'}}^{*}$ states containing two heavy quarks and one up or down quark are affected by the medium, considerably. The parameters of the $Ω_{Q Q^{'}}^{*}$ states containing two heavy quarks and one strange quark, however, do not show any sensitivity to the density of the cold nuclear medium. We also discuss the variations of the vector self-energy at each channel with respect to the changes in the density. The negative shifts in the mass of $Ξ_{Q Q^{'}}^{*}$ states due to nucleons in the medium can be used to study the doubly heavy baryons' interactions with the nucleons. The results obtained can also be used in analyses of the results of the future in-medium experiments.

Dihedral flavor group as the key to understand quark and lepton flavor mixing
Jun-Nan Lu🇨🇳 · Gui-Jun Ding🇨🇳
We have studied the lepton and quark mixing patterns which can be derived from the dihedral group $D_{n}$ in combination with CP symmetry. The left-handed lepton and quark doublets are assigned to the direct sum of a singlet and a doublet of $D_{n}$ . A unified description of the observed structure of the quark and lepton mixing can be achieved if the flavor group $D_{n}$ and CP are broken to $Z_{2} \times C P$ in neutrino, charged lepton, up quark and down quark sectors, and the minimal group is $D_{14}$ . We also consider another scenario in which the residual symmetry of the charged lepton and up quark sector is $Z_{2}$ while $Z_{2} \times C P$ remains preserved by the neutrino and down quark mass matrices. Then $D_{7}$ can give the experimentally favored values of CKM and PMNS mixing matrices.

Soft modifications to jet fragmentation in high energy proton-proton collisions
Christian Bierlich🇩🇰
The discovery of collectivity in proton-proton collisions, is one of the most puzzling outcomes from the two first runs at LHC, as it points to the possibility of creation of a Quark-Gluon Plasma, earlier believed to only be created in heavy ion collisions. One key observation from heavy ion collisions is still not observed in proton-proton, namely jet-quenching. In this letter it is shown how a model capable of describing soft collective features of proton-proton collisions, also predicts modifications to jet fragmentation properties. With this starting point, several new observables suited for the present and future hunt for jet quenching in small collision systems are proposed.

Orbital Angular Momentum at Small $x$
Yuri V. Kovchegov🇺🇸
We determine the small Bjorken $x$ asymptotics of the quark and gluon orbital angular momentum (OAM) distributions in the proton in the double-logarithmic approximation (DLA), which resums powers of $α_{s} ln^{2} (1/ x)$ with $α_{s}$ the strong coupling constant. Starting with the operator definitions for the quark and gluon OAM, we simplify them at small $x$ , relating them, respectively, to the polarized dipole amplitudes for the quark and gluon helicities defined in our earlier works. Using the small- $x$ evolution equations derived for these polarized dipole amplitudes earlier we arrive at the following small- $x$ asymptotics of the quark and gluon OAM distributions in the large- $N_{c}$ limit: \begin{align} L_{q + \bar{q}} (x, Q^2) = - \Delta \Sigma (x, Q^2) \sim \left(\frac{1}{x}\right)^{\frac{4}{\sqrt{3}} \, \sqrt{\frac{\alpha_s \, N_c}{2 \pi}} }, \ \ \ \ \ L_G (x, Q^2) \sim \Delta G (x, Q^2) \sim \left(\frac{1}{x}\right)^{\frac{13}{4 \sqrt{3}} \, \sqrt{\frac{\alpha_s \, N_c}{2 \pi}}} . \end{align}

Multicomponent meson superfluids in chiral perturbation theory
Luca Lepori🇮🇹 · Massimo Mannarelli🇮🇹
We show that the multicomponent meson systems can be described by chiral perturbation theory. We chiefly focus on a system of two pion gases at different isospin chemical potential, deriving the general expression of the chiral Lagrangian, the ground state properties and the spectrum of the low-energy excitations. We consider two different kinds of interactions between the two meson gases: one which does not lock the two chiral symmetry groups and one which does lock them. The former is a kind of interaction that has already been discussed in mutlicomponent superfluids. The latter is perhaps more interesting, because seems to be related to an instability. Although the pressure of the system does not show any instability, we find that for sufficiently strong locking, the spectrum of one Bogolyubov mode becomes tachyonic. This unstable branch seems to indicate a transition to an inhomogeneous phase.

Ratio of strange to $u / d$ momentum fraction in disconnected insertions
Jian Liang🇺🇸 · Mingyang Sun🇺🇸 · Yi-Bo Yang🇨🇳 · Terrence Draper🇺🇸 · Keh-Fei Liu🇺🇸
The ratio of the strange quark momentum fraction $⟨ x ⟩_{s + s ˉ}$ to that of light quark $u$ or $d$ in disconnected insertions (DI) is calculated on the lattice with overlap fermions on four domain wall fermion ensembles. These ensembles cover three lattice spacings, three volumes and several pion masses including the physical one, from which a global fitting is carried out. A complete nonperturbative renormalization and the mixing between the quark and glue operators are taken into account. We find the ratio to be $⟨ x ⟩_{s + s ˉ} / ⟨ x ⟩_{u + u ˉ} (DI) = 0.795 (79) (77)$ at $μ = 2$ GeV in the $MS$ scheme. This ratio can be used as a constraint to better determine the strange parton distribution especially in the small $x$ region in the global fittings of PDFs when the connected and disconnected sea are fitted and evolved separately, demonstrating a new way that connects lattice calculations with global analyses.

Spotting hidden sectors with Higgs binoculars
Monika Blanke🇩🇪 · Simon Kast🇩🇪 · Jennifer M. Thompson🇩🇪 · Susanne Westhoff🇩🇪 · José Zurita🇩🇪
We explore signals of new physics with two Higgs bosons and large missing transverse energy at the LHC. Such a signature is characteristic of models for dark matter or other secluded particles that couple to the standard model through an extended scalar sector. Our goal is to provide search strategies and an interpretation framework for this new signature that are applicable to a large class of models. To this end, we define simplified models of hidden sectors leading to two different event topologies: symmetric decay, i.e., pair-produced mediators decaying each into a Higgs plus invisible final state; and di-Higgs resonance, i.e., resonant Higgs-pair production recoiling against a pair of invisible particles. For both scenarios, we optimize the discovery potential by performing a multi-variate analysis of final states with four bottom quarks and missing energy, employing state-of-the-art machine learning algorithms for signal-background discrimination. We determine the parameter space that the LHC can test in both scenarios, thus facilitating an interpretation of our results in terms of complete models. Di-Higgs production with missing energy is competitive with other missing energy searches and thus provides a new opportunity to find hidden particles at the LHC.

Asymmetric heavy-quark hadroproduction at LHCb: Predictions and applications
Rhorry Gauld🇳🇱 · Ulrich Haisch🇩🇪 · Benjamin D. Pecjak🇬🇧
We present a phenomenological analysis of asymmetric bottom- and charm-quark production within the LHCb acceptance relevant for $pp$ collisions at $s = 13 TeV$ . Predictions are provided for both anti- $k_{t}$ bottom- and charm-jet pairs, which are kept differentially with respect to the invariant mass of the jet pair. It is quantified how data in this region can provide sensitivity to the couplings of the $Z$ boson to heavy quarks, and we investigate what precision is needed to compete with LEP. We also discuss how asymmetry and rate measurements can provide constraints on a particular class of new-physics models, which contains gauge bosons with small/moderate couplings to light/heavy quarks and masses of the order of $100 GeV$ . Predictions are obtained including all relevant QCD and QED/weak contributions up to next-to-leading order, which have been implemented in a Fortran code which allows to directly compute the asymmetric cross sections. We provide all relevant analytic formulas for our computations.

Neutrino Mistakes: Wrong tracks and Hints, Hopes and Failures
Maury C Goodman🇺🇸
In the last two decades, the field of neutrino physics has made enormous progress in measuring the strength and frequency of neutrino and antineutrino oscillations. Along the way, there have been many instances of misunderstanding which led to wrong measurements or speculation for new features of neutrino physics that are not now accepted as correct. This is part of the natural process of science, but given the well-accepted notion that we learn from our mistakes, it is worthwhile to look at some examples and see what the lessons might be. With that goal in mind, I have a list of results which might be termed neutrino mistakes, with the fact in mind that there is no well-accepted definition of a mistake, and no unique threshold for counting something as a mistake when you change your mind after you obtain more information. After making the list, I chose seven of them to discuss. No clear conclusions were drawn from this exercise, but some interesting issues regarding putative wrong results are discussed.

Nuclear coalescence from correlation functions
Kfir Blum🇮🇱 · Masahiro Takimoto🇮🇱
We derive a simple formula relating the cross section for light cluster production (defined via a coalescence factor) to the two-proton correlation function measured in heavy-ion collisions. The formula generalises earlier coalescence-correlation relations found by Scheibl & Heinz and by Mrowczynski for Gaussian source models. It motivates joint experimental analyses of Hanbury Brown-Twiss (HBT) and cluster yield measurements in existing and future data sets.

Implementing the three-particle quantization condition including higher partial waves
Tyler D. Blanton🇺🇸 · Fernando Romero-López🇪🇸 · Stephen R. Sharpe🇺🇸
We present an implementation of the relativistic three-particle quantization condition including both $s$ - and $d$ -wave two-particle channels. For this, we develop a systematic expansion about threshold of the three-particle divergence-free K matrix, $K_{df, 3}$ , which is a generalization of the effective range expansion of the two-particle K matrix, $K_{2}$ . Relativistic invariance plays an important role in this expansion. We find that $d$ -wave two-particle channels enter first at quadratic order. We explain how to implement the resulting multichannel quantization condition, and present several examples of its application. We derive the leading dependence of the threshold three-particle state on the two-particle $d$ -wave scattering amplitude, and use this to test our implementation. We show how strong two-particle $d$ -wave interactions can lead to significant effects on the finite-volume three-particle spectrum, including the possibility of a generalized three-particle Efimov-like bound state. We also explore the application to the $3 π^{+}$ system, which is accessible to lattice QCD simulations, where we study the sensitivity of the spectrum to the components of $K_{df, 3}$ . Finally, we investigate the circumstances under which the quantization condition has unphysical solutions.

Recent Progress on the QCD Phase Diagram
Sayantan Sharma🇮🇳
Recent progress and the latest results on the bulk thermodynamic properties of QCD matter from lattice are reviewed. In particular, I will stress upon the fact that lattice techniques are now entering into precision era where they can provide us with new insights on even the microscopic degrees of freedom in different phases of QCD. I will discuss some instances, from the recent studies of topological fluctuations and screening masses. The progress towards understanding the effects of anomalous $U_{A} (1)$ symmetry on the chiral crossover transition and transport properties of QCD matter will also be discussed.

Long-term evolutions of the cyclotron line energies in Her X-1, Vela X-1 and Cen X-3 as observed with Swift/BAT
Long Ji🇩🇪 · Ruediger Staubert🇩🇪 · Lorenzo Ducci🇩🇪 · Andrea Santangelo🇩🇪 · Shu Zhang🇨🇳 · Zhi Chang🇨🇳
We study the long-term evolution of the centroid energy of cyclotron lines - often referered to as Cyclotron Resonance Scattering Features (CRSF) - in Her X-1, Vela X-1 and Cen X-3, using survey observations of the Burst Alert Telescope (BAT) onboard Swift. We find a significant decrease of the fundamental CRSF energy in Her X-1 and the first harmonic line energy in Vela X-1, since the launch of Swift in 2004 and until 2010 and 2012, respectively.In both sources the decreases stopped at some time, with a quite stable centroid energy thereafter. Unlike in Her X-1 and Vela X-1, the CRSF energy in Cen X-3 does not show a long-term decrease. It is observed not to change for at least the past 14 years. The long-term variation of the line energy is a direct way to investigate the magnetic field structure in the polar regions of pulsars. Our results may stimulate the development of theoretical models, especially regarding to how the accreted mass accumulates in the accretion mound or how the magnetic field distorts around the polar cap.

Lattice QCD determination of neutron-antineutron matrix elements with physical quark masses
Enrico Rinaldi🇺🇸 · Sergey Syritsyn🇺🇸 · Michael L. Wagman🇺🇸 · Michael I. Buchoff🇺🇸 · Chris Schroeder🇺🇸 · Joseph Wasem🇺🇸
Matrix elements of six-quark operators are needed to extract new physics constraints from experimental searches for neutron-antineutron oscillations. This work presents in detail the first lattice quantum chromodynamics calculations of the necessary neutron-antineutron transition matrix elements including calculation methods and discussions of systematic uncertainties. Implications of isospin and chiral symmetry on the matrix elements, power counting in the isospin limit, and renormalization of a chiral basis of six-quark operators are discussed. Calculations are performed with a chiral-symmetric discretization of the quark action and physical light quark masses in order to avoid the need for chiral extrapolation. Non-perturbative renormalization is performed, including a study of lattice cutoff effects. Excited-state effects are studied using two nucleon operators and multiple values of source-sink separation. Results for the dominant matrix elements are found to be significantly larger compared to previous results from the MIT bag model. Future calculations are needed to fully account for systematic uncertainties associated with discretization and finite-volume effects but are not expected to significantly affect this conclusion.

Diamond Detectors for Direct Detection of Sub-GeV Dark Matter
Noah Kurinsky🇺🇸 · To Chin Yu🇺🇸 · Yonit Hochberg🇮🇱 · Blas Cabrera🇺🇸
We propose to use high-purity lab-grown diamond for the detection of sub-GeV dark matter. Diamond targets can be sensitive to both nuclear and electron recoils from dark matter scattering in the MeV and above mass range, as well as to absorption processes of dark matter with masses between sub-eV to 10's of eV. Compared to other proposed semiconducting targets such as germanium and silicon, diamond detectors can probe lower dark matter masses via nuclear recoils due to the lightness of the carbon nucleus. The expected reach for electron recoils is comparable to that of germanium and silicon, with the advantage that dark counts are expected to be under better control. Via absorption processes, unconstrained QCD axion parameter space can be successfully probed in diamond for masses of order 10 eV, further demonstrating the power of our approach.
