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 develops a Green-function formalism based on multiparticle theory to describe sequential and virtual two-proton decay, successfully applying it to the 45Fe nucleus to simultaneously reproduce experimental decay widths and proton angular distributions by appropriately selecting the shell potential.
This paper proposes that repulsive interactions mediated by a dark-sector vector portal can stiffen the equation of state for hyperonic compact stars within the modified quark-meson coupling model, thereby resolving the hyperon puzzle and allowing these stars to reach observed two-solar-mass limits while offering new multimessenger tests for dark matter interactions.
This study employs Bayesian inference to demonstrate that while SU(6) hyperonic models produce equations of state too soft to satisfy neutron star observational constraints, the more flexible SU(3) framework yields stiffer, observationally consistent results that remain statistically indistinguishable from purely nucleonic scenarios with current data.
This paper demonstrates that by optimizing the exponentiated-Hamiltonian decomposition for product-formula algorithms, the T-gate cost of simulating quantum chromodynamics in the electric basis can be reduced by a factor of nearly , effectively removing an exponential-in- overhead previously attributed to the method.
This paper employs kinetic rate equations within (3+1)D viscous hydrodynamic simulations to demonstrate that while rapid inelastic suppression and regeneration dominate bottomonium dynamics at LHC energies, the smaller regeneration effect at RHIC, combined with nuclear absorption, explains why production magnitudes are comparable at both colliders despite the LHC's higher temperatures.
This paper establishes a quantitative framework linking local spin polarization and quantum entanglement in two-qubit systems by deriving a closed-form upper bound on concurrence that is saturated by pure states, and demonstrates its application to the process where polarization significantly constrains maximal entanglement.
This paper presents the first application of unbiased exponential resummation to (2+1)-flavor lattice QCD at physical quark masses, yielding consistent determinations of the QCD pseudocritical temperature and curvature coefficient that validate the method as a reliable approach for probing the QCD crossover at small finite baryon density.
This paper reports the discovery and analysis of three rotational glitches in the previously quiet young pulsar PSR J1637$-$4642, observed over a 15-year period, with modeling of the largest event supporting the standard superfluid vortex-creep paradigm and demonstrating that even "quiet" pulsars can exhibit substantial glitch activity.
This paper demonstrates that color triality constraints on vacuum hadronization allow the simultaneous measurement of conserved current flows (electric charge, baryon number, and strangeness) in jets to directly probe nonperturbative QCD parameters, specifically the diquark-to-quark production ratio and strange-to-light pair-production ratio, while satisfying the Gell-Mann–Nishijima relation.
Using the covariant Nambu-Jona-Lasinio model with Schwinger proper-time regularization, this study investigates the skewness and momentum transfer dependence of pion and kaon generalized parton distributions, finding that valence-quark distributions are strongly suppressed by increasing momentum transfer and skewness (especially at lower scales) while gluon distributions show weak dependence on both, with results at specific scales aligning well with experimental data, global JAM analyses, and lattice-QCD calculations.
