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 study demonstrates that a hybrid neutron star model incorporating hyperons, deconfined quark matter, and bosonic sexaquark dark matter with a mass of approximately 1900 MeV successfully satisfies all current observational constraints on mass, radius, and tidal deformability.
This paper proposes a method to locate the QCD critical point by analyzing contours of constant entropy density extrapolated from zero net-baryon density, yielding a predicted critical point at MeV and MeV based on Wuppertal–Budapest lattice QCD data.
This paper demonstrates that generalized higher-form symmetries, exemplified by axion electrodynamics, drive a novel self-similar inverse cascade that organizes non-equilibrium turbulent systems into large-scale coherent structures through universal scaling behavior.
This high-statistics lattice QCD study at a heavy pion mass ( MeV) demonstrates that di-nucleons do not form bound states, attributing previous claims of deeply bound states to misidentifications of the spectrum arising from off-diagonal correlation function elements rather than physical hexaquark states.
This paper derives a Burgers-type evolution equation for the bulk viscous pressure in unpaired quark matter, identifying four key transport coefficients based on electroweak decay rates and evaluating them across different equations of state to provide a new framework for simulating dissipation in compact star mergers.
This paper introduces a Bayesian Inverse Uncertainty Quantification (IUQ) approach for nuclear data adjustment within the OECD/NEA WPNCS SG14 benchmark, demonstrating its superior ability to replicate nonlinear model responses compared to traditional GLLS and MOCABA methods while validating the utility of low-correlation experiments for data assimilation.
This paper demonstrates that proton-proton scattering at specific kinematic conditions (151 MeV, 90°) naturally generates a high-fidelity Bell-triplet entangled state, enabling a proposed quantum teleportation protocol that utilizes the strong interaction's intrinsic Hamiltonian to perform Bell measurements.
This paper presents a model-independent analysis of radiative corrections to the decay using dispersion relations to extend previous chiral perturbation theory results, thereby enabling a precise calculation of isospin-breaking corrections for the two-pion contribution to the muon's anomalous magnetic moment.
This paper reveals that higher-order cumulants mixing elliptic and triangular flow in Pb+Pb collisions exhibit a surprising simplicity at fixed impact parameter, where their variations are solely determined by the mean elliptic flow from the collision geometry, leading to analytic relations that agree well with CMS data and enable predictions for higher-order cumulants.
This study extends the level scheme of 8B up to 10 MeV by analyzing invariant-mass data from 9C and 13O beam experiments, identifying new levels and decay pathways, and demonstrating strong correspondence between these experimental findings and ab initio symmetry-adapted no-core shell model predictions for positive parity states below 8.4 MeV.
