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 proposes and analyzes lepton double charge exchange reactions (X) at multi-GeV accelerator facilities as a feasible and powerful probe for lepton number violation and physics beyond the Standard Model, predicting sizable cross sections driven by left-right mixing and heavy neutral leptons that are free from the constraints of traditional decay or capture experiments.
Motivated by color coherence and decoherence effects, this paper proposes a theoretical framework combining vacuum-like evolution and medium-induced radiation to successfully describe the inclusive jet modification factor and its substructure dependence in 0–10% PbPb collisions at as measured by ATLAS.
Using first-principles lattice simulations with an exact center symmetry induced by a specific imaginary isospin chemical potential, this study demonstrates that QCD with three degenerate dynamical quarks undergoes a first-order deconfinement phase transition and maps its behavior in the mass-isospin chemical potential plane.
This study applies the Random Forest algorithm to successfully reproduce observed decay modes and half-lives in superheavy nuclei, predicting that alpha decay will dominate for elements Z=119–122 while identifying a potential long-lived spontaneous fission island southwest of Fl.
This paper introduces a Universal Four-Fermion Formation Framework (U4F) combined with large-scale configuration-interaction calculations to explain the origin of a newly identified global odd-even staggering in decay as a result of suppressed clustering correlations caused by unpaired nucleons.
This study analyzes the causal constraints of the Mueller-Israel-Stewart theory for heat flow in heavy-ion collisions, revealing that realistic conditions lead to causality-violating heat fluxes that suggest either an overestimation of transport coefficients or a breakdown of the fluid approximation.
This paper demonstrates that an emulator based on eigenvector continuation can significantly accelerate coupled-channels calculations for sub-barrier fusion reactions while accurately extracting nuclear deformation parameters, thereby providing a powerful tool for systematically exploring intrinsic nuclear shapes.
This paper proposes that the global hyperon polarization observed in low-energy heavy-ion collisions can be partially explained (accounting for ~23% of the signal) by a mechanism linking it to long-standing transverse polarization phenomena via the alignment of production and reaction planes driven by directed flow, rather than solely by quark-gluon plasma vorticity.
This paper introduces the quarkyonic QMC (QQMC) model, which combines a dual quarkyonic picture with the quark-meson coupling framework to demonstrate that nuclear interactions significantly enhance the stiffening of the equation of state and trigger an earlier onset of quark saturation in dense matter compared to noninteracting models.
By combining high-precision liquid-state -NMR measurements of short-lived K with advanced atomic and nuclear theories, this study successfully determines the spatial distribution of nuclear magnetization and reveals a persistent overestimation of spin contributions in current nuclear models, thereby establishing a robust method for benchmarking nuclear structure theory and searching for physics beyond the Standard Model.
