    Factorization of elastic, single, and double diffractive scattering

    Philipp B. Aretz🇺🇸 · Kyle Lee🇺🇸 · Stella T. Schindler🇺🇸 · Iain W. Stewart🇺🇸

    We use effective field theory techniques to factorize elastic, single, and double diffractive forward scattering in the Regge limit , where is the squared momentum transfer. These processes involve a large rapidity gap and comprise about half the total cross section. We explain why the diffractive PDFs appearing in diffraction do not appear as universal hadronic functions for diffraction. For , we show that the hadronic functions in and diffraction differ, and hence are non-universal. In general, we prove that rapidity anomalous dimensions are universal between diffractive and processes, and that color-singlet (Pomeron) evolution equations can be determined at the amplitude level.

    Azimuthal momentum isotropization in the Quark-Gluon Plasma thermalization

    Sergio Barrera Cabodevila🇩🇪 · Xiaojian Du🇨🇳 · Carlos A. Salgado🇪🇸 · Bin Wu🇪🇸

    Azimuthal anisotropies coming from the initial state of a heavy-ion collision have been historically disregarded in the study of thermalization because they are expected to be rapidly washed out due to final-state interactions. However, they may be important when one attempts to describe azimuthal correlations observed in the collisions of small systems. In this work, we study how these initial anisotropies relax in the context of the Boltzmann Equation in Diffusion Approximation (BEDA). We find a clear hierarchy in the relaxation time of the anisotropies in terms of each harmonic coefficient. We also explore the evolution of the -dependent harmonic coefficients in time, finding a shift in the initial peak towards higher momenta that mimics the experimental data when we perform a phenomenologically motivated simulation.

    Ghost Hunting in the Yang-Mills Vacuum

    Seth Grable🇺🇸

    In this work, I analyze the zero modes of a one-loop semiclassical Yang-Mills theory in \(3+1\)d. I find that zero modes are generated by gauge redundancy of the background field. Proper gauge fixing, achieved by introducing a bosonic ghost term, together with zeta-function regularization, yields a finite one-loop effective action in closed form that reproduces the well-known one-loop Yang-Mills beta function.

    Nuclear Many-Body Systems as Benchmarks for Quantum Computing

    Sota Yoshida🇯🇵 · Alessandro Baroni🇺🇸 · Takayuki Miyagi🇯🇵 · Ermal Rrapaj🇺🇸

    We present a framework for benchmarking quantum algorithms for nuclear many-body systems based on realistic nuclear Hamiltonians such as chiral effective field theory. To this end, we introduce a workflow that maps nuclear interactions in second quantization formalism to qubit Hamiltonians. This enables the systematic construction of benchmark instances spanning no-core and valence-space formulations with two-body (NN) and selected three-body (3N) interactions. Then, we proceed to provide resource estimates for three representative eigenvalue algorithms: Quantum Phase Estimation, Quantum Krylov methods, and Observable Dynamic Mode Decomposition. We compare their resource requirements in terms of T-gate counts and system size, and examine the impact of model-space choices and many-body interactions. The primitives included in our analysis are Trotterization, Qubitization, and Quantum Singular Value Transformation. Our results quantify scaling trends across algorithms and problem classes, and provide a basis for consistent comparisons of quantum approaches to nuclear many-body problems. The implementation is provided by the NuQuLib software stack.

    Heavy quark coalescence probability in the presence of a potential

    Taesoo Song🇩🇪 · Jiaxing Zhao🇩🇪

    In this study, we explore the role of the heavy quark potential in heavy quark coalescence, whose probability is expected to be unity at low momentum. To this end, we develop a phenomenological heavy quark potential based on the constituent quark model that reproduces the vacuum masses of pseudoscalar and vector heavy mesons. Using this potential, we demonstrate its enhancement effect on the coalescence probability. We also investigate how medium-induced modifications of the heavy quark potential in the quark gluon plasma affect the coalescence process. Our results indicate that the coalescence probability remains close to unity as long as the modification of the potential is sufficiently moderate.
