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 demonstrates that the systematic quenching observed in nucleon-removal reaction cross sections arises from dynamical effects—specifically non-additive interactions and polarization potentials omitted in standard additive models—rather than genuine nuclear-structure correlations, a conclusion validated by four-body CDCC calculations for Li.
This paper provides an introduction and overview of light meson form factors, covering their classical and quantum field theory foundations, main theoretical methods, and specific discussions on pion, kaon, eta, and eta' form factors.
This paper systematically investigates the phase structure of the BCS-BEC crossover in asymmetric nuclear matter, demonstrating that while isospin asymmetry generally suppresses homogeneous superfluidity, the combined effects of angle-dependent gaps and Fulde-Ferrell-Larkin-Ovchinnikov states can significantly mitigate phase separation and lift orientational degeneracy in the high-density BCS regime, whereas these mechanisms vanish in the low-density BEC regime where phase separation persists.
This paper investigates subleading D-like three-nucleon forces arising from tree-level single-pion exchange and contact interactions at fifth order in the chiral expansion, demonstrating that while the general potential requires 16 low-energy constants, it can be effectively approximated by just 4 constants if the intermediate excitation mechanism is assumed to dominate.
This paper proposes that non-prompt photons emitted via rotating synchrotron radiation from a rigidly rotating, magnetized quark-gluon plasma can explain the observed excess of direct photons and their elliptic flow, thereby offering a potential resolution to the "direct photon puzzle."
This paper investigates homogeneous nuclear matter using an \textit{ab initio} Self-consistent Green's function approach based on chiral effective field theory, demonstrating strong agreement with coupled-cluster theory for the equation of state while providing detailed insights into single-particle properties and dynamics.
While recent advancements in 3D multidimensional simulations have significantly validated the neutrino-driven explosion mechanism and enabled comprehensive modeling of core-collapse supernovae from collapse to remnant, critical uncertainties regarding explosion criteria, progenitor effects, magnetic fields, neutrino physics, and the equation of state continue to challenge definitive predictions of stellar outcomes.
This white paper outlines a strategic five-year roadmap, informed by community surveys and the EuCAIF initiative, to overcome barriers like limited resources and expertise by defining critical infrastructure, training, and funding needs for integrating AI across particle, nuclear, and astroparticle physics.
This study investigates the substructure of the resonance using a quark model framework and finds that its helicity amplitude is significantly influenced by an component, challenging the conventional view of the resonance as a pure state.
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.
