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 demonstrates that quantum-inspired deep neural networks (QDNNs) offer superior predictive accuracy and tighter uncertainties compared to classical methods for extracting Compton form factors from JLab experimental data, establishing them as an efficient tool for future multidimensional studies of hadronic structure.
This paper demonstrates that while global multiplicity fluctuations introduce a constant vertical offset in the differential radial flow observable , only the shape of this distribution (or its derivative) contains genuine physical information about radial-flow dynamics, rendering its zero-crossing point physically insignificant.
This paper demonstrates that an ultralight scalar dark matter field coupling to neutrinos can significantly amplify the rate of lepton-flavour-violating muon-to-positron conversion in nuclei, thereby enabling upcoming experiments to establish stringent new constraints on neutrino-dark matter couplings that surpass current cosmological and terrestrial limits.
This study utilizes astrophysical observations, including massive pulsar measurements, NICER data, and GW170817 tidal deformability constraints alongside perturbative QCD calculations, to significantly restrict the admissible parameter space for the equation of state of cold, dense strongly interacting matter.
This paper introduces an energy-localized Brink-Axel hypothesis variant of the shell model Lanczos strength-function method to efficiently compute radiative strength functions for use in Hauser-Feshbach reaction codes, demonstrating its validity on Mg and revealing that while M1 and E1 transitions significantly contribute below the photo-absorption threshold in Fe, current model spaces cannot fully reproduce the low-energy strength observed in Oslo-type experiments.
This paper proposes that the clustering of resonance poles observed in scattering by Hoehler may be partially an artifact of the pole extraction procedure, specifically arising from effective partial-wave mixing induced by the necessary truncation of the partial-wave series.
This pedagogical review chapter summarizes first-principles lattice QCD simulations and effective theory calculations regarding the thermodynamics of magnetized quark-gluon matter under extreme conditions of high temperature, density, and strong electromagnetic fields, which are relevant to heavy-ion collisions, neutron stars, and the early Universe.
This contribution employs principal component analysis to decompose event-by-event spectral fluctuations in heavy-ion collisions into distinct thermal and geometric normal modes, establishing a physical analogy to molecular vibrations that explains key experimental observables such as and the sign change at low in .
This paper presents refined calculations of low-energy absorption on Ar using a hybrid HF-CRPA and statistical de-excitation model, revealing that the standard MARLEY model overestimates DUNE event yields by approximately 20% while potentially improving the feasibility of supernova pointing due to a more pronounced overestimation at backward angles.
This paper demonstrates that while different nuclear mass models predict varying equilibrium compositions in the deepest layers of a neutron star's outer crust, these differences propagate only weakly to global observables, resulting in less than a one percent variation in the properties of crust-dominated neutron stars and confirming the robustness of modern models for astrophysical applications.
