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 investigates the late-time asymptotic behavior and attractor structure of spin density in minimal causal spin hydrodynamics under Gubser flow, demonstrating that in specific regimes, spin density decays as a hydrodynamic mode governed by late-time scaling laws similar to conventional thermodynamic variables.
This study investigates the interaction of accelerator neutrinos up to 55 MeV with I nuclei at the SNS, calculating cross sections that reveal the dominant contribution of the Gamow-Teller resonance GTR-1 (60–80%) alongside significant effects from higher resonances GTR-2 and AR-2, with theoretical results showing agreement with experimental data below the neutron separation threshold.
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 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 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 extends a previous analysis of photoproduction by incorporating LEPS spin density matrix element data to constrain the theoretical model, revealing that while the resonance is essential, the role of -channel exchange is ambiguous and contradicts earlier claims of its dominance.
This paper proposes a theoretical framework that models the vacuum as a meson field to derive the interaction energy and force between two parallel metal plates, drawing an analogy to the nuclear force between nucleons described in Quantum Hadrodynamics.
This paper presents a high-accuracy theoretical study of the 7Be(p,γ)8B reaction in the astrophysical energy range using a novel ab initio framework that combines the No-Core Shell Model and Cluster Channels Orthogonal Functions Method with R-matrix theory to calculate the astrophysical S-factor, evaluate result reliability, and identify dominant reaction mechanisms.
