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 a quark-meson framework incorporating temperature-dependent quark masses and anomalous magnetic moments to reconcile lattice QCD magnetic susceptibility data with theoretical models, demonstrating that quark degrees of freedom must emerge significantly below the QCD cross-over temperature (around 120 MeV) to explain the observed paramagnetism.
This study utilizes the JYFLTRAP double Penning trap to precisely measure the electron-capture value of Sn, identifying a favorable allowed transition to a low-lying excited state in In that, when combined with advanced atomic corrections, significantly enhances sensitivity for future electron neutrino mass measurements.
This paper utilizes the large- limit to argue that the QCD phase diagram features at least three distinct phases at both zero and high baryon densities, where low-temperature thermodynamics is described by a parameter-free 3D string model and a high-density "Quarkyonic" phase is distinguished by its unique chiral properties.
This study employs deformed relativistic Hartree-Bogoliubov theory, phenomenological Woods-Saxon fits, and Glauber reaction cross-section calculations to establish a quantitative criterion for halo identification, confirming Ne as the most prominent halo candidate within the neutron-rich Ne isotopic chain through its anomalously large surface diffuseness and enhanced interaction cross sections.
Using a coalescence model coupled with the MUSIC hybrid framework, this study investigates the elliptic and triangular flow of light (anti-)(hyper-)nuclei in Pb+Pb collisions at 5.36 TeV, revealing the breakdown of simple constituent scaling at high transverse momentum, the insensitivity of hypertriton flow to internal structure, and providing predictions for comparison with ALICE experimental data.
This paper presents the first calculation of tensor and axial-tensor mesons with total spin within the Covariant Spectator Theory, utilizing a refined quark-antiquark interaction kernel with momentum-dependent strong coupling to successfully describe the mass spectrum of heavy and heavy-light mesons using only eight adjustable parameters.
This paper proposes using forward-backward multiplicity asymmetry (FBMA) in uranium-uranium collisions as a robust control parameter to effectively disentangle the Chiral Magnetic Effect signal from flow-induced backgrounds by leveraging the correlation between FBMA and initial-state geometry while largely decoupling it from magnetic field correlations.
This paper generalizes the alpha-nucleus nonlocality effect to odd-A and odd-odd nuclei within the two-potential approach framework, utilizing an XGBRegressor to optimize parameters and significantly improve the accuracy of alpha-decay half-life predictions for superheavy nuclei.
This paper demonstrates that the universality of the shear viscosity to entropy density ratio in Unruh radiation is fundamentally linked to causality, establishes a saturation of the bulk viscosity bound, and derives a novel sum rule for spectral densities that connects thermal isotropy in Rindler space to the validity of Pascal's law.
This study employs a generalized least squares (GLS) updating approach to generate fission yield covariance matrices from major nuclear data libraries, demonstrating that incorporating these correlations significantly reduces decay heat uncertainty and shifts the dominant error source from fission yields to decay energy data.
