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 applies Principal Component Analysis to the residuals of six nuclear mass models and finds that their discrepancies are largely uncorrelated and model-specific, suggesting that future improvements should be guided by individual model analyses rather than a universal approach.
This paper extends the Impulse Approximation for generalized parton distributions (GPDs) of spin-0 composite hadrons by utilizing a light-front Wigner function to incorporate target symmetries and identify a novel angular momentum transfer coupling, subsequently applying this framework to He to predict experimental signatures of composite structure.
This paper resolves the longstanding challenge of incorporating nuclear shell effects into orbital-free density functional theory by developing a non-local kinetic energy density functional that successfully reproduces shell behaviors consistent with exact Kohn-Sham solutions.
This paper presents an extension of the MadGraph5_aMC@NLO framework that enables automated leading-order calculations for S-wave quarkonium and leptonium production within NRQCD and NRQED formalisms, offering seamless integration with Beyond the Standard Model scenarios and highlighting the necessity of careful theoretical analysis beyond simple velocity-scaling rules.
This paper introduces a computationally efficient method that integrates normalizing flows to incorporate equation-of-state-informed priors into NICER pulse profile modeling, thereby tightening neutron star mass-radius constraints and revealing new geometric modes while enabling a more robust joint inference of pulsar parameters and dense matter physics.
This study employs ab initio many-body methods (IMSRG and CC) alongside RPA to calculate isoscalar monopole sum rules in finite nuclei, demonstrating strong agreement between approaches and deriving nuclear matter incompressibility values consistent with phenomenological ranges.
This paper introduces an efficient and highly accurate method for representing nuclear densities using an orthogonal basis set derived from Principal Component Analysis of relativistic continuum Hartree-Bogoliubov calculations, which significantly outperforms traditional Fourier-Bessel and Sum-of-Gaussians approaches in convergence and precision.
This paper employs an Effective Field Theory framework to derive a factorization formula for inclusive jet production in dense media, demonstrating that both the Landau-Pomeranchuk-Migdal effect and color decoherence are governed by a single dimensionless parameter and can be systematically incorporated into jet quenching phenomenology through multi-sub-jet operators.
A fixed-target program at the Electron-Ion Collider would significantly advance nuclear physics by providing high-statistics data to constrain cold nuclear matter effects, map the QCD phase diagram at low energies, and measure critical cross sections for space radiation protection.
This paper proposes introducing a new class of spin-2 massive mesons into covariant density functional theory to enhance the isovector spin-orbit sector, offering a potential solution to the discrepancies between nuclear model predictions and experimental data from PREX and CREX regarding neutron-rich skins.
