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 unified Khuri-Treiman formalism that combines production effects and final-state interactions to analyze COMPASS's "freed-isobar" data on the decay, successfully extracting the relative strengths and phases of production mechanisms to enable a future precise determination of the pole position.
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.
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.
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 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.
This paper computes the 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.
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.
This study utilizes the EPOS4 model to demonstrate that hadronic interactions, specifically the competition between rescattering and regeneration, significantly modify resonance production yields and distributions in both small (pp, p-O) and large (O-O, Pb-Pb) collision systems at LHC energies, highlighting the critical role of the hadronic phase even in small systems.
This paper proposes a novel one-parameter empirical formula, BECR, which leverages binding energy correlations and structural corrections to accurately model nuclear charge radii, achieving a root-mean-square deviation of 0.0138 fm on experimental data and enabling predictions for over 11,000 nuclei.
This paper calculates substantial and positive next-to-next-to-leading order (NNLO) QCD corrections for pion- and kaon-induced exclusive Drell-Yan processes within the generalized parton distribution framework, establishing the necessity of including these higher-order effects for reliable theoretical predictions to match future J-PARC experimental data.
This paper presents rigorous exact calculations of infinite nucleonic matter using the full configuration-interaction quantum Monte Carlo method, revealing that symmetric nuclear matter is strikingly strongly correlated and challenging the validity of previous many-body expansion truncations.
