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.

(2+2)D Collective Model based on a relativistic Boltzmann equation in the Isotropization Time Approximation: CoMBolt-ITA

This paper presents CoMBolt-ITA, a new (2+2)D collective model based on the relativistic Boltzmann equation in the isotropization time approximation that successfully couples pre-equilibrium dynamics with hydrodynamics to simulate quark-gluon plasma evolution, demonstrating strong consistency with standard hydrodynamic and hybrid models for small shear viscosity while revealing significant discrepancies and nontrivial thermalization effects for larger viscosity values.

Re-visiting thermal effects on stellar neutron capture reactions using a novel quantum dynamical approach

This study employs a novel time-dependent coupled channels wave-packet (TDCCWP) method to demonstrate that accounting for temperature-dependent initial states in neutron capture reactions leads to decreased cross sections and reaction rates for 188^{188}Os, a finding that contrasts with traditional Hauser-Feshbach predictions and has significant implications for understanding the rapid neutron capture process.

Probing the three-body force in hadronic systems with specific charge parity

This paper proposes that three-body forces are definitively necessary in specific three-body hadronic systems with certain charge parities, demonstrating through contact-range potential calculations that while these forces play a minor role in the DˉsDK\bar{D}_sDK system, they are crucial for determining whether the DˉDη\bar{D}^*D\eta system forms a bound state.

String-breaking statics and dynamics in a (1+1)D SU(2) lattice gauge theory

This paper develops and applies a gauge-invariant tensor-network toolkit based on the loop-string-hadron formulation to systematically study both static string tension and the complex dynamical processes of string breaking, including particle production and entanglement spreading, in a (1+1)D SU(2) lattice gauge theory with dynamical fermions.

Photon production from gluon splitting and fusion induced by a magnetic field in heavy-ion collisions

This paper investigates the direct photon puzzle in peripheral heavy-ion collisions by calculating the one-loop photon production from gluon splitting and fusion induced by strong magnetic fields during the pre-equilibrium stage, finding that splitting dominates at low energies and that longitudinal anisotropy has a negligible effect on the yield, which is then compared with PHENIX experimental data.
