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 and compares magnetic moments, quadrupole moments, and transition strengths ( and ) for N=50 isotones calculated using the newly developed p35-i3 Hamiltonian and related variants, assessing their performance against experimental data to evaluate theoretical uncertainties in ab-initio derived shell model interactions.
This paper investigates relativistic effects in femtoscopic correlations and deuteron formation, demonstrating that transforming the source function to the center-of-mass frame to account for relativistic elongation resolves discrepancies between theoretical predictions and experimental data regarding the deuteron coalescence coefficient.
This study demonstrates that incorporating rigorous angular momentum conservation into the IBUU transport model significantly enhances pion production and reduces the charged pion yield ratio in intermediate-energy heavy-ion collisions, a crucial correction for accurately extracting the nuclear symmetry energy at high densities.
Using the extended two-flavor Nambu–Jona-Lasinio model with the Ginzburg-Landau approximation and a Landau-level regularization scheme, this study reveals that increasing isospin chemical potential in a magnetic field drives a transition from pion superfluidity at low fields to a novel rho superconductivity phase at high fields, highlighting a significant interplay between QCD and QED.
This paper demonstrates that a qubit-regularized SU(3) lattice gauge theory on a plaquette chain admits a continuum limit governed by a parafermion conformal field theory, yielding a massive one-dimensional model of glueballs with specific mass ratios and string tension values.
Motivated by the ATOMKI anomalies, this study employs the Gaussian Expansion Method to predict X17-induced Lamb shifts and hyperfine splittings in muonic atoms up to Z=15, identifying specific isotopes like muonic deuterium, helium ions, and silicon-29 as promising probes to distinguish between vector and pseudoscalar fifth-force mediators.
This paper investigates how isospin symmetry breaking influences cusp structures in hadron scattering near closely separated thresholds, proposing a practical amplitude representation that links neighboring cusps through isospin symmetry to decode the properties of near-threshold exotic hadrons.
This paper argues that while auxiliary counterterms are redundant for encoding physical information since they only ensure exact cutoff independence, they remain valuable tools for resolving renormalization inconsistencies and improving the convergence of effective field theory expansions.
Using first-principles lattice simulations of SU(3) Yang-Mills theory in Rindler spacetime, this study demonstrates that weak acceleration induces a spatially inhomogeneous confinement-deconfinement phase transition where distinct phases coexist, with a phase boundary consistent with theoretical predictions and a critical temperature matching that of non-accelerated gluodynamics.
This study evaluates the sensitivity of actinide fission yields to macroscopic liquid-drop model prescriptions by comparing the Lublin–Strasbourg Drop (LSD) and ISOLDA models, finding that while both reproduce gross isotopic patterns, LSD offers superior agreement with experimental data for heavy fragments and that the spread between the two models provides a practical estimate of macroscopic-model uncertainty.
