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 a scale setting and strong coupling determination for 2+1 flavor lattice QCD using HISQ ensembles, reporting precise gradient flow scales ( and ) and a potential scale () while providing a polynomial ansatz for predicting lattice spacings and estimating .
This paper introduces a physics-embedded Bayesian neural network (PE-BNN) framework that integrates an energy-independent phenomenological shell factor and WAIC-based hyperparameter optimization to accurately predict energy-dependent fission product yields with fine structures and close agreement with known nuclear shell effects.
This study utilizes the AMPT model to demonstrate that the elliptic flow of charged hadrons in 200 GeV d+Au collisions is primarily driven by early-stage partonic interactions rather than hadronic rescattering, successfully reproducing experimental trends and highlighting the significance of parton scattering mechanisms in asymmetric collision systems.
This paper investigates how magnetic fields in heavy ion collisions induce quarkonia spin alignment through both orbital wave function distortion and spin state mixing, finding that the spin contribution dominates phenomenologically while the subleading orbital effect offers a unique probe for studying quarkonium structural changes.
This theoretical study predicts the existence of well-isolated, deeply bound atoms with narrow widths and demonstrates that reactions on light nuclei are a highly effective method for observing these states as discrete peaks, thereby offering new insights into -nucleus interactions.
This paper demonstrates that shock-induced density and temperature perturbations in core-collapse supernovae and neutron star mergers can overcome electron mass damping to sustain the chiral plasma instability and generate substantial ohmic heating via the chiral magnetic effect.
This paper generalizes the jet transport coefficient to a Lorentz-covariant diffusion tensor to describe momentum broadening in out-of-equilibrium media, revealing new energy-momentum correlations and demonstrating that non-equilibrium corrections can either enhance or reduce broadening depending on the initial distribution.
This paper analyzes the missing-energy spectrum from monochromatic neutrino-C interactions measured by the JSNS collaboration using a relativistic distorted-wave approach with an improved spectral function, while discussing the roles of nuclear recoil, final-state interactions, and neutrino event generators in describing low-energy nuclear effects.
This paper summarizes the achievements of the MexNICA Collaboration, established in 2016 to coordinate Mexican participation in the MPD-NICA experiment at JINR, highlighting their contributions to the development of the miniBeBe trigger detector and advances in phenomenological and theoretical studies of the baryon-rich QCD phase diagram.
This paper presents a self-consistent coupled transport framework for open and hidden charm in a strongly coupled quark-gluon plasma, utilizing thermodynamic -matrix interactions constrained by lattice QCD to simultaneously describe charm-quark diffusion and charmonium kinetics, thereby successfully reproducing LHC Pb-Pb collision observables.
