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 quark-meson coupling model with in-medium loop contributions, this study predicts significant mass reductions of approximately 60 MeV for -wave charmonia () in cold nuclear matter at normal density, while finding no level crossing with the threshold up to three times normal density, a phenomenon potentially observable at FAIR and RHIC.
This paper demonstrates through Bayesian inference that quarkyonic matter equations of state are consistent with current neutron star observations and identifies specific mass-radius signatures, such as curve curvature and central sound speed, that can distinguish neutron stars with quarkyonic cores from those without.
This paper analyzes the capture in the Li reaction using an effective operator to demonstrate that isoscalar transitions from an initial wave are forbidden without distortion, resulting in a negligible -factor at small energies where the dominant contribution arises from transitions to isospin 1 components of the ground state.
This review comprehensively examines how state-of-the-art *ab initio* nuclear many-body calculations of radiative, recoil-order, and isospin-breaking corrections for light nuclei enable precision tests of the Standard Model and searches for physics beyond it, particularly in determining and identifying exotic weak currents.
This paper presents a new calculation of the astrophysical S-factor for the p-p fusion reaction, yielding a value approximately one order of magnitude lower than accepted standards by utilizing a genetic algorithm-optimized inverse scattering potential and an exact WKB action integral that accounts for the specific shape of the interaction rather than relying on the bare Coulomb approximation.
This paper presents a general framework for predicting electron capture rates in using exact leptonic wave functions and a non-factorized treatment of the transition matrix element to quantify non-factorization effects and compare theoretical predictions for , , and ratios with current experimental data.
This paper presents a novel framework using absorbing Markov chains and Hierarchical Bayesian analysis to precisely compute and decompose uncertainties in -ray feeding probabilities for the Mg(p,)Al reaction, thereby improving the accuracy of astrophysical Al production rate predictions.
This paper introduces the Schrödinger Generator, a novel framework that combines adaptive marginal mapping with normalizing flows and a resampling step to achieve stable, unbiased, and scalable high-dimensional integration and sampling for complex quantum many-body systems, successfully demonstrating its efficacy on nuclear states with over 600 dimensions.
This paper argues that the recently introduced reducible-basis renormalization method has generated misconceptions regarding the QCD trace anomaly, thereby obscuring its established, regulator-independent, and scheme-free nature and leading to flawed interpretations of nucleon mass and internal forces.
By integrating ab initio nuclear lattice effective field theory densities with a deformed Glauber model, this study demonstrates that accounting for intrinsic deformation significantly improves the theoretical description of reaction cross sections and momentum distributions for beryllium isotopes, particularly the halo nucleus 11Be, without relying on single-particle orbital assumptions.
