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 establishes a Bayesian uncertainty quantification framework to calibrate deformed Woods-Saxon potentials for proton radioactivity, demonstrating that propagating parametric uncertainties not only accurately predicts experimental half-lives but also reveals a direct correlation between error profile volatility and nuclear structural softening near shell closures.
This paper proposes an extended quarkyonic matter framework incorporating strange quarks and the full baryon octet, demonstrating that the quarkyonic mechanism lowers the critical density for hyperon appearance while significantly stiffening the equation of state to resolve the hyperon puzzle and increase the maximum mass of hyperon stars.
By reparameterizing the Polyakov-loop extended Nambu--Jona-Lasinio model to align with lattice data and the BES-II energy range, this study demonstrates that a distinct dip in the second-order temperature cumulant along the freeze-out line near 7.7 GeV supports the hypothesis that the non-monotonic transverse momentum correlations observed by the STAR Collaboration are linked to the QCD critical endpoint.
This paper investigates saturation effects in exclusive vector meson production within the Color Glass Condensate framework using a hotspot model, finding that while saturation has mild impacts at current energy and charge-density levels, its suppressive effect on scattering cross sections becomes more prominent as the proton's internal color-charge density increases.
This paper establishes rigorous, model-independent Lorentz-covariant bounds on relaxation spectra and hydrodynamic convergence in thermal quantum field theory, demonstrating that boosted non-hydrodynamic gaps and spectral widths increase with velocity rather than simply undergoing time dilation, a result verified numerically in super-Yang-Mills plasma.
This paper proposes a novel, track-only method for extracting nucleon transversity by utilizing the transverse charge distribution in fragmenting quarks, which suppresses unpolarized backgrounds and coherently enhances spin-dependent azimuthal asymmetries through the Collins effect.
This paper demonstrates that a uniform wounded parton Glauber model, assuming four partons per nucleon and incorporating negative binomial fluctuations, successfully describes charged particle multiplicity distributions across O+O, Ne+Ne, Xe+Xe, and Pb+Pb collisions at TeV using a single set of parameters for centralities up to approximately 1%.
This study employs Bayesian inference and information-theoretic measures to demonstrate that future neutron star radius measurements with a precision of approximately 0.2 km are sufficient to extract nearly all available information for identifying twin neutron stars, marking the point of diminishing scientific returns for distinguishing hadron-quark phase transitions.
This study employs Skyrme Hartree-Fock calculations within a potential model to demonstrate that the branching ratio of beta-delayed proton emission from Be is highly sensitive to the precise energy of a narrow resonance near the proton-emission threshold in B, reaching up to and necessitating experimental confirmation of whether this resonance lies below 200 keV.
This paper proposes a nuclear quantum battery utilizing collective excitation of Fe nuclei in a hard X-ray waveguide, where a self-consistent waveform-engineering protocol inhibits radiative decay to achieve superlinear charging with an energy density scaling as .
