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 employs a two-flavor holographic hard-wall model with holographic renormalization to investigate dense QCD matter at zero temperature, revealing a high-density baryonic phase with a nearly vanishing chiral condensate that yields an equation of state capable of supporting neutron stars with masses exceeding two solar masses.
This paper investigates how the reflectivity and phase shift of a storage bottle wall influence the sensitivity of ultracold neutron experiments searching for neutron-antineutron oscillations, highlighting the critical role of optimizing the antineutron pseudopotential and proposing methods to determine it.
This study investigates the impact of early-time charm quark dynamics on D-meson observables in Pb+Pb collisions at TeV using the IP-Glasma+MUSIC+UrQMD framework and finds that despite significant momentum broadening in the pre-equilibrium stage, the nuclear modification factor () and elliptic flow () of D-mesons remain only weakly sensitive to these early interactions.
This study employs a refined AMPT transport model with adjusted beauty quark mass and flavor-specific coalescence parameters to successfully reproduce LHCb and ALICE data on beauty and non-prompt charm hadron production in 13 TeV $pp$ collisions, offering new insights into heavy quark dynamics and hadronization mechanisms in small collision systems.
This paper extends the shell-model Monte Carlo method to actinides, successfully calculating their nuclear state and level densities in large model spaces and demonstrating strong agreement with experimental data while revealing significant enhancements over mean-field predictions.
By applying the BK equation to model gluon occupancy and entropy, this study demonstrates that while protons remain below the unitarity bound, heavy nuclei reach the "saturon" limit at small , identifying nuclei as the optimal environment for observing this high-occupancy QCD phenomenon.
This paper proposes that ultra-peripheral ion collisions generate entangled multi-particle states through shared photon polarization, leading to distinct azimuthal angular correlations that differ significantly between classical and quantum predictions and offer new avenues for testing multi-particle entanglement.
This study investigates the electromagnetic polarizabilities of singly heavy mesons and doubly heavy baryons using heavy hadron chiral perturbation theory, predicting anomalously large electric polarizabilities for mesons due to near-degenerate - mass thresholds and establishing heavy diquark-antiquark symmetry to unify the chiral dynamics of these systems.
This paper demonstrates that Physics-Informed Neural Networks (PINNs) can accurately solve the many-body Schrödinger equation for the deuteron ground state using realistic nucleon-nucleon interactions, achieving a relative binding energy error of approximately compared to established numerical benchmarks.
This paper demonstrates that background rotation catalyzes the chiral magnetovortical instability by splitting Alfvén waves into magneto-Coriolis modes, one of which becomes unstable even under weak chiral vortical effects, potentially enabling new dynamo mechanisms in rotating chiral plasmas.
