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.

Rank-2 Electromagnetic Backgrounds and Angular Momentum Barriers in Gravitomagnetic Spin-Quadrupole Searches

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.

Interaction between nuclear clusters and superfluid phonons in the neutron-star inner crust

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.

Inclusive J/ψJ/ψ productions in pp collisions at s=\sqrt{s}= 5.02, 7, and 13 TeV with the PACIAE model

This study utilizes the PACIAE 4.0 model, which incorporates both color-singlet and color-octet NRQCD contributions alongside cluster collapse and bb-hadron decays, to successfully simulate inclusive J/ψJ/\psi 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.

New Physics Searches via Beam Normal Spin Asymmetry in Bhabha Scattering

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.

Proton induced reactions on 118Sn target at energies up to 18 MeV

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.

Controlled Gate Networks: Theory and Application to Eigenvalue Estimation

This paper introduces controlled gate networks, a quantum circuit design strategy that significantly reduces the number of two-qubit gates required for linear combinations of unitary operators, and demonstrates its effectiveness in variational calculations, eigenvalue estimation via the rodeo algorithm, and lattice nucleon time evolution through both theoretical analysis and experimental implementation on real quantum hardware.
