Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents ab initio Glauber theory calculations for high-energy nuclear scattering observables in p+12C, 12C+12C, and 6He+12C systems using variational Monte Carlo wave functions, demonstrating excellent agreement with experimental data and revealing that the cumulant expansion of the phase-shift function converges rapidly up to the second order.
This paper analyzes curvature invariants across a broad ensemble of neutron star equations of state, revealing that negative Ricci scalars are surprisingly common in massive, compact stars, while also refining the quasi-universal mass relation and determining the conditions under which the trace anomaly vanishes or becomes negative.
This paper presents a self-consistent generalization of a novel method for calculating three-dimensional Bose-Einstein correlation functions with Coulomb final-state interactions to non-spherical source functions, thereby validating previous spherical approximations and providing a new software package for these computations.
This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.
This paper demonstrates that accounting for hadrons produced via ion electromagnetic dissociation, which break experimental exclusivity vetos, resolves long-standing tensions between theoretical predictions and LHC measurements for exclusive muon pair and coherent production.
This study utilizes the AMPT-SM model to demonstrate that while initial-state nuclear deformation in $Ne+Ne$ collisions at 5.36 TeV induces minor variations (2–6%) in bulk observables, particularly in peripheral events, the overall particle production and collective dynamics are primarily governed by system density and interaction mechanisms rather than geometric deformation.
This study employs a Poincaré-covariant contact interaction model to derive the equation of state for strange quark stars, demonstrating that specific parameter sets for interaction strength and ultraviolet cutoff yield mass-radius relations and tidal deformabilities consistent with multi-messenger astrophysical observations.
Using the two-flavor Linear Sigma Model with quarks at one-loop order, this study demonstrates that the chiral phase transition at zero temperature and finite baryon density is of first order, occurring when the chemical potential equals the vacuum quark mass, as evidenced by discontinuities in the chiral condensate, particle masses, couplings, and the speed of sound.
This paper solves the Dyson-Schwinger equations for the Landau gauge quark-gluon vertex in quenched QCD to demonstrate that while its transverse form factors exhibit weak angular dependence, this does not constitute planar degeneracy, while simultaneously confirming that dynamical chiral symmetry breaking relies on a mutually generated tensor coupling and that the resulting quark propagator is consistent across different Yang-Mills solutions with poles only on the real time-like axis.
