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 a microscopic Skyrme quasiparticle vibration (QPVC) model to calculate -decay widths in superfluid nuclei, successfully applying it to predict the decay from the giant dipole resonance to the state in Ce with results consistent with recent experimental data.
This study investigates how global rotation in ultra-relativistic heavy-ion collisions modifies chemical freeze-out parameters within the hadron resonance gas model, revealing that rotation systematically lowers freeze-out temperatures and suggesting that hadron yield ratios are more sensitive indicators of these rotational effects than conventional cumulant ratios.
This paper utilizes the EPOS4+CATS framework to dynamically generate non-Gaussian emission sources for charmonium-proton pairs in high-energy pp collisions, enabling the first femtoscopic extraction of charmonium-nucleon interactions while revealing that feed-down from excited states introduces significant uncertainties in prompt -proton correlation measurements.
This study quantitatively assesses the contribution of coherent photon-nuclear interactions, driven by strong electromagnetic fields in relativistic heavy-ion collisions, as a distinct background source that mimics chiral magnetic effect signals to improve the precision of separating genuine CME signals from background noise.
Using the SMASH transport model, this study demonstrates that the hadron resonance gas equation of state successfully reproduces experimental global hyperon polarization data at low collision energies, revealing a potential polarization peak around GeV and confirming that helicity polarization vanishes due to space-reversal symmetry.
This study integrates the quark-meson coupling (QMC) model into the DJBUU transport code to demonstrate its effectiveness in simulating intermediate-energy heavy-ion collisions, showing comparable performance to traditional QHD for bulk observables while requiring specific adjustments to in-medium production cross-sections to accurately reproduce pion yields in neutron-rich systems.
This paper implements the quark-meson coupling model within the Daejeon Boltzmann-Uehling-Uhlenbeck transport framework to simulate Au+Au collisions at intermediate energies, comparing the resulting maximum densities with those from a conventional quantum hadrodynamics model to highlight differences in predicted nuclear matter properties.
This paper reports preliminary work on simulating heavy-ion collisions using the DaeJeon Boltzmann-Uehling-Uhlenbeck (DJBUU) and Sindong Quantum Molecular Dynamics (SQMD) models executed on high-performance computers to address the computational demands of understanding dense nuclear matter.
This paper presents a comprehensive theoretical calculation of the magnetic moments for open heavy-flavor ( and ) molecular pentaquark octets within a constituent quark model, revealing distinct electromagnetic signatures that differentiate between symmetric and antisymmetric light-diquark configurations and provide crucial benchmarks for identifying these states in future experiments.
This paper presents an analytically solvable, semi-analytical framework for calculating medium-induced parton splittings with full energy fraction and angular dependence in the large- limit, while also introducing and validating an improved semi-hard approximation that offers a robust alternative to the widely used but often unreliable soft-gluon approximation.
