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.
Using the AMPT-HC model, this study proposes a phenomenological direct-production mechanism for resonances in Au+Au collisions at GeV to explain how early production and subsequent daughter rescattering in a high-baryon-density medium lead to a predicted increase in the ratio toward central collisions.
This paper reports the first proof-of-principle demonstration of precision -delayed charged-particle spectroscopy at FRIB using , successfully reconstructing its decay scheme, assigning spins and parities to excited states in via spectral interference patterns, and comparing the extracted -strength distribution with shell-model calculations.
This paper reveals that in magnetized two-flavor color-superconducting quark matter, Landau quantization suppresses conventional Fermi-surface contributions to the Meissner effect, leading to a topologically constrained response governed by the quantum metric of the lowest Landau level that scales with the pairing gap rather than the chemical potential, with potential implications for magnetar oscillations.
This paper presents an EOS-driven extension of the NSCool thermal evolution code that unifies the treatment of nucleonic, hyperonic, and quark degrees of freedom within a single workflow, incorporating updated neutrino emissivity and heat capacity calculations for mixed-phase compact stars.
This paper demonstrates that -factorization in the Color Glass Condensate represents only the zeroth order of a systematic gradient expansion, revealing that higher-order corrections involving transverse derivatives of source distributions generate intrinsic initial-state momentum anisotropies and a more complete energy-momentum tensor that are missed by leading-order approximations.
Using the basis light-front quantization formalism, this study reveals that relativistic effects induce novel "W"-shaped structures in the leading-twist distribution amplitudes of -wave axial vector quarkonia, highlighting the necessity of relativistic frameworks for accurately modeling heavy quarkonium production and structure.
This paper utilizes the operator product expansion within Pionless effective field theory to analyze high-momentum nucleon distributions in light nuclei, successfully extracting local-operator matrix elements from variational Monte Carlo data to accurately reconstruct single-nucleon distributions and establish approximate relations between single- and two-nucleon contributions in potentials lacking explicit non-nucleon degrees of freedom.
This paper applies transfer learning to fine-tune deep neural networks pretrained on carbon-12 data, successfully constructing robust, data-driven models for inclusive electron-nucleus cross sections across various nuclei that outperform existing phenomenological models while systematically analyzing the impact of fine-tuning depth, data availability, and kinematic coverage.
This study demonstrates that Kolmogorov-Arnold networks (KANs) significantly outperform traditional models in predicting nuclear binding energies with a low error of 0.26 MeV while simultaneously providing interpretable analytical expressions that align with classical nuclear physics theories.
This paper proposes a novel mechanism within the Energy Density Functional framework, attributing the origin and evolution of nuclear magic numbers to the interplay between the Dirac mass kinetic term (arising from spin-0 boson participation) and the spin-orbit term, thereby offering a unified explanation for shell structures in both stable and exotic nuclei.
