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 introduces Systematic Analytic Regularization (SAR), a novel scheme that regularizes quantum field theories by analytically continuing the power of the kinetic operator at the action level to ensure formal finiteness, and demonstrates its self-consistent application to and Yukawa theories at next-to-leading order.
This paper presents the first measurement of open-charm baryon-to-meson ratios, specifically the baseline, in + collisions at RHIC energies using the high-statistics, unbiased dataset collected by the sPHENIX experiment to investigate heavy-flavor hadronization mechanisms.
This paper presents a theoretical study of charged current -induced deep inelastic scattering on at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.
This paper employs self-consistent Hartree-Fock+RPA and Subtracted Second RPA models incorporating realistic pairing and tensor correlations to investigate spin-isospin excitations, address the quenching of magnetic dipole and Gamow-Teller transitions via 2p-2h configurations, and calculate -decay lifetimes for semi-magic and magic nuclei.
Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.
This paper calculates charged-current quasielastic-like neutrino and antineutrino scattering cross-sections on C using the coherent density fluctuation model with a relativistic effective mass and two-nucleon emission, providing predictions for accelerator experiments like MiniBooNE, T2K, and MINERvA while analyzing the axial form factor and momentum transfer dependencies.
This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.
This study utilizes the PHQMD approach with a novel momentum-dependent potential to demonstrate that a soft, momentum-dependent nuclear equation of state best reproduces experimental flow data for protons and light clusters in intermediate-energy heavy-ion collisions, while also revealing distinct flow signatures that can help discriminate between different cluster formation mechanisms.
This paper extends the solution of the Balitsky-Kovchegov equation with full impact-parameter dependence to nuclear targets, providing predictions for key processes like deep-inelastic scattering and diffractive vector meson production to investigate gluon saturation and nuclear structure effects relevant for future facilities like the EIC and current LHC studies.
This study presents the first simultaneous Bayesian inference of temperature-dependent heavy-quark spatial diffusion and jet transport coefficients in quark-gluon plasma using LHC D-meson data, revealing a non-monotonic temperature dependence in their ratio and establishing a data-driven quantitative relationship between these fundamental transport properties.
