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 investigates the transport properties of mesons in a hadronic medium using Tsallis non-extensive statistics, revealing that drag and diffusion coefficients increase with temperature, the non-extensive parameter , and mass cutoffs, while the spatial diffusion coefficient decreases with these factors and suggests an upper limit of to remain consistent with AdS/CFT bounds.
This paper interprets the LHCb observation of the meson as the chiral partner of the ground state , thereby validating the chiral doubling scenario for heavy-light hadrons and predicting the existence of a yet-unobserved narrow beauty-strange meson at approximately 5747 MeV.
This paper investigates the bound and resonance states of the hypernuclei He, Li, and Be using a three-cluster model, identifying a set of narrow and wide resonances with total widths as low as 10 keV and revealing their dominant decay channels.
This paper proposes and validates a method for extracting Hamiltonian energy eigenvalues from quantum-generated real-time correlators using the generalized eigenvalue problem, demonstrating through simulations and hardware tests that it is substantially more efficient than Fourier transform-based approaches.
This study employs time-dependent density functional theory to reveal that the early-stage dynamics of neutron-induced fission in U within both the ground and isomeric wells are strongly dissipative, exhibiting distinct mass asymmetry behaviors—rapid stabilization in the ground state versus large-amplitude harmonic oscillations in the isomeric well—along with rare neutron emission.
This paper investigates the evolution of proto-hybrid stars by deriving hot hybrid equations of state under various charge conservation and neutrino trapping conditions, revealing that the early stages of a hybrid star's life critically influence its maximum gravitational mass in later stages.
This paper identifies a previously unrecognized empirical regularity in the low-energy spectra of odd-mass nuclei that serves as a reliable signature for octupole collectivity in neighboring even-even systems, offering a simple guide for selecting promising candidates for future experiments and theoretical studies.
This study extracts neutron radii for Mg isotopes by combining Glauber model reaction cross-section calculations with a semiphenomenological core+n description to validate a one-neutron halo structure in Mg and predict a two-neutron halo-like structure in Mg.
This chapter provides a pedagogical overview of neutrino-nucleus scattering in the medium-energy regime, detailing the fundamental electroweak formalism, dominant interaction mechanisms, and critical nuclear effects that drive systematic uncertainties in modern accelerator-based neutrino oscillation experiments.
This paper investigates the thermodynamic and transport properties of hot and dense quantum chromodynamic matter using three effective frameworks, revealing that the Lorenz ratio increases rapidly at low baryon chemical potential while the shear-viscosity-to-entropy-density ratio gradually rises with density, exhibiting qualitative similarities to the electron-hole plasma in graphene.
