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 that quantum entanglement serves as a unifying foundation for statistical and high-energy physics, arguing that systems naturally evolve toward a Maximal Entanglement Limit where thermalization and probabilistic behaviors emerge from the geometry of high-dimensional Hilbert spaces without requiring ergodicity or classical randomness.
This paper demonstrates the feasibility of incorporating Fermi-Dirac statistics into boost-invariant perfect spin hydrodynamics simulations for spin-1/2 particles, revealing that while the resulting corrections are an order of magnitude smaller than spin feedback effects, the approach requires careful handling as numerical solutions can break down under extreme spin polarization.
This paper challenges the recent MAMI collaboration's determination of the hypertriton binding energy by proposing that the observed sharp pion-momentum line instead originates from the weak decay of the ground state of hyperhelium-7 into lithium-7.
This paper presents precise mass measurements of neutron-deficient Cd isotopes using ISOLTRAP at CERN to determine the shell gap at and constrain the mass surface near Sn, revealing an enhancement of the shell gap towards the doubly magic nucleus that challenges state-of-the-art theoretical models.
This paper investigates how neutron decays into dark baryons affect bulk viscosity in neutron star mergers, finding that while the standard slow decay rate only slightly reduces viscosity, a faster decay rate could significantly enhance it and rapidly dampen merger oscillations.
This paper extends a previously developed generally covariant formalism to incorporate the diffusion of conserved charges, while clarifying the apparent distinction between chemical potential and diffusion terms.
This paper introduces Systematic Analytic Regularization (SAR), a novel scheme that regularizes quantum field theories by analytically continuing the power of the kinetic operator at the action level to ensure formal finiteness, and demonstrates its self-consistent application to and Yukawa theories at next-to-leading order.
This paper presents the first measurement of open-charm baryon-to-meson ratios, specifically the baseline, in + collisions at RHIC energies using the high-statistics, unbiased dataset collected by the sPHENIX experiment to investigate heavy-flavor hadronization mechanisms.
This paper presents a theoretical study of charged current -induced deep inelastic scattering on at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.
This paper employs self-consistent Hartree-Fock+RPA and Subtracted Second RPA models incorporating realistic pairing and tensor correlations to investigate spin-isospin excitations, address the quenching of magnetic dipole and Gamow-Teller transitions via 2p-2h configurations, and calculate -decay lifetimes for semi-magic and magic nuclei.
