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 presents a detailed comparison of the SuSAv2 and RDWIA theoretical models against experimental measurements of charged-current neutrino-induced single-pion production from T2K, MINERvA, and MiniBooNE across a broad energy range, highlighting their respective approaches to modeling nuclear targets and pion production channels.
This paper analyzes the angular momentum selection rules and identifies four dominant electromagnetic background barriers that constrain spectroscopic searches for gravitomagnetic spin-quadrupole coupling in highly charged ions, ultimately deriving the specific multi-isotope experimental topology required to isolate the gravitational signal and establishing a preliminary laboratory bound on the gyrogravitational ratio.
This paper employs nuclear density functional theory to derive a microscopic description of the interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust, revealing a significantly smaller coupling constant than previous hydrodynamical estimates due to the suppression of phonon amplitude within the clusters.
This paper constructs self-gravitating, singularity-free baryonic tube solitons in an Einstein non-linear sigma model coupled to -mesons, demonstrating that increasing the number of flavors enhances physical predictions by reducing binding energy despite increasing total energy.
This study utilizes the PACIAE 4.0 model, which incorporates both color-singlet and color-octet NRQCD contributions alongside cluster collapse and -hadron decays, to successfully simulate inclusive production in proton-proton collisions at 5.02, 7, and 13 TeV and provide a quantitative analysis of the relative contributions and rescattering effects across various production mechanisms.
This paper investigates the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond-the-Standard-Model mediators within the JLab polarized positron program, highlighting how the observable's unique zero crossing in the Standard Model provides a clean, background-free opportunity to significantly extend search ranges for scalar and vector new physics scenarios.
This paper utilizes Ultra-Relativistic Quantum Molecular Dynamics (UrQMD) simulations to demonstrate that the three-dimensional two-pion emission source in intermediate-mass Ar+Sc collisions at SPS energies is well-described by Lévy-stable distributions, thereby establishing a theoretical baseline for future femtoscopy measurements in such systems.
This paper develops theoretical diagnostics for the breakdown of mean-field theory, demonstrating how spatial structure and finite interaction ranges qualitatively alter the effective description and renormalization-group flow.
This study investigates proton-induced reactions on an enriched 118Sn target up to 18 MeV using the stacked-foil activation technique, reporting first-time cross-section measurements for specific channels and revealing discrepancies between experimental data and theoretical models regarding composite-particle emission.
This paper presents a multi-dimensional Langevin model that dynamically simulates the time evolution of fissioning nuclei with stochastic neutron emission, enabling the calculation and comparison of pre-scission neutron multiplicities, fragment mass distributions, and neutron energy spectra against experimental data.
