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.

Effect of the near-proton-emission threshold resonance in $^{11}$ B on the branching ratio of beta-delayed proton emission from $^{11}$ Be

This study employs Skyrme Hartree-Fock calculations within a potential model to demonstrate that the branching ratio of beta-delayed proton emission from $^{11}$ Be is highly sensitive to the precise energy of a narrow resonance near the proton-emission threshold in $^{11}$ B, reaching up to $10^{-5}$ and necessitating experimental confirmation of whether this resonance lies below 200 keV.

Collective Enhancement of Nuclear Excitation for a Nuclear Quantum Battery

This paper proposes a nuclear quantum battery utilizing collective excitation of $^{57}$ Fe nuclei in a hard X-ray waveguide, where a self-consistent waveform-engineering protocol inhibits radiative decay to achieve superlinear charging with an energy density scaling as $n\sqrt{n}$ .

Solar-System Abundances of $p$ -Nuclides Probe Collective Neutrino Oscillations in Supernovae

This study demonstrates that collective neutrino oscillations occurring within 10 km of the proto-neutron star surface in core-collapse supernovae significantly enhance the production of specific proton-rich nuclides, thereby resolving discrepancies between theoretical models and observed solar-system abundances.

Nonequilibrium approach to heavy-quark transport

This paper presents a nonequilibrium Green's function approach to heavy-quark transport within the Kadanoff-Baym framework, demonstrating that off-shell and memory effects significantly influence heavy-quark dynamics in quark-gluon plasmas, particularly near the critical temperature.

Production Effects and Final-state Interactions in $\pi_1 \to 3\pi$

This paper presents a unified Khuri-Treiman formalism that combines production effects and final-state interactions to analyze COMPASS's "freed-isobar" data on the $\pi_1(1600) \to 3\pi$ decay, successfully extracting the relative strengths and phases of production mechanisms to enable a future precise determination of the $\pi_1$ pole position.

Bayesian Inference for Extracting Barrier Distributions from Fusion Excitation Functions

This paper introduces a Bayesian inference framework using AutoBNN to robustly extract barrier distributions with well-calibrated uncertainties from sparse fusion excitation function data, outperforming Gaussian process regression in benchmarks and successfully mitigating spurious structures in experimental heavy-ion fusion reactions.

Toponium Spectrum in the Complex-Energy Plane

This paper employs a T-matrix approach with a Cornell potential to analyze the toponium spectrum in the complex-energy plane, investigating how the system's bound-state poles evolve from small to realistic top-quark widths and assessing the role of the confining force in light of recent LHC threshold enhancements.

A self-consistent Higgs-portal framework for dark matter--admixed neutron stars: Collider-motivated benchmarks meet multimessenger constraints

This paper proposes a self-consistent single-fluid relativistic mean-field framework for dark matter-admixed neutron stars using a Higgs-portal model with a massive $Z^\prime$ mediator, demonstrating how the resulting repulsive interaction dynamically couples baryonic and dark matter sectors to systematically soften the equation of state, reduce maximum stellar mass, and establish a direct link between collider-motivated WIMP models and multimessenger astrophysical constraints.

Relativistic corrections and high-energy resummation for exclusive heavy quarkonium photoproduction

This paper computes the $O(v^2)$ relativistic correction to the high-energy resummed coefficient function for exclusive heavy quarkonium photoproduction, finding that while the correction itself is negligible at the physical mass scale, it significantly improves prediction robustness by partially canceling the factorization scale dependence of the leading-order relativistic correction.

Radiative corrections in neutral-current (anti)neutrino elastic scattering at $\text{GeV}$ energies I: Nucleon targets

This paper introduces radiative corrections within an effective field theory framework for neutral-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these corrections are comparable in magnitude to strange quark contributions and yield excellent agreement with BNL E734 and MiniBooNE experimental data.
