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 the first microscopic prediction of reaction observables for the two-neutron halo candidates F and Na by combining the deformed relativistic Hartree-Bogoliubov theory in continuum with a validated Glauber reaction model, confirming their dilute halo structures through agreement with experimental cross sections and characteristic momentum distributions.
Using the Bethe-Salpeter formalism within the impulse approximation, this paper computes the isospin-breaking baryonic form factors for pions and kaons, yielding a baryonic radius of 0.043(2) fm for the pion that aligns with dispersive benchmarks and predicting larger radii of approximately 0.26 fm for kaons that are compatible with chiral QCD models.
This paper presents calculations of space-like electromagnetic form factors and charge radii for both light and heavy-light pseudoscalar mesons using a flavor-dependent Bethe-Salpeter framework.
This paper constructs a family of exactly solvable relativistic kinetic theories in 1+1 dimensions that continuously interpolate between Fickian and Cattaneo diffusion via a tunable scattering parameter, enabling the analytical derivation of the full quasinormal mode spectrum to explicitly track the transition from purely diffusive to damped propagating modes.
This paper presents a novel, numerically and formally exact solution to the pion Bethe-Salpeter equation in the chiral limit, utilizing state-of-the-art QCD correlation functions while strictly satisfying axial Ward-Takahashi identities.
This paper presents a unified microscopic framework based on a symmetry-restored multi-excitation generator coordinate method to derive non-local optical potentials from an effective Hamiltonian, successfully applying it to calculate neutron scattering cross sections for deformed chromium isotopes while consistently treating nuclear structure and reaction observables.
This Letter introduces the multiplicity-conditioned energy-energy correlator (EEC) jet function and demonstrates through a next-to-leading order factorization calculation that the EEC's angular structure acquires a multiplicity-dependent anomalous dimension, thereby providing a robust perturbative probe of multiplicity fluctuations and aiding in the isolation of bias effects in nuclear environments.
This paper predicts that the spin Hall effect in hot and dense QCD matter, induced by baryon chemical potential gradients in heavy-ion collisions, can be detected through the distinct sign and beam energy dependence of the second Fourier coefficients of net hyperon spin polarization using a (3+1)D viscous hydrodynamic model.
Using time-domain terahertz emission spectroscopy, researchers observed a dynamic magneto-chiral instability in photoexcited tellurium, where an electric current parallel to a magnetic field amplifies electromagnetic waves, offering a promising mechanism for THz-wave amplification in chiral materials.
This paper introduces a hierarchical framework combining ab initio many-body calculations with Bayesian neural networks to create accurate, uncertainty-quantified emulators for predicting nuclear properties across isotopic chains and performing global sensitivity analysis of nuclear forces.
