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 physics-based method for generating probability tables by calculating fluctuating cross sections using a Gaussian Orthogonal Ensemble -matrix model, validating the approach with U and Pu to show qualitative agreement with conventional Breit-Wigner formalism while accounting for statistical uncertainties and -matrix unitarity.
This study investigates the macroscopic properties and universal relations of proto-neutron stars within Energy-Momentum Squared Gravity, revealing that while thermodynamic variables and the modified gravity parameter significantly alter individual stellar characteristics, the underlying correlations between these properties remain robust and largely unaffected.
This study utilizes state-of-the-art 3D lattice covariant density functional theory to calculate uranium densities for hydrodynamic simulations of relativistic U+U collisions, revealing a tension between elliptic flow and transverse-momentum observables regarding effective quadrupole deformation while highlighting the challenges of constraining octupole deformation due to uncertainties in reference nuclear structures.
This paper investigates radial oscillations in nucleonic, quarkyonic, and hybrid neutron stars by incorporating out-of-equilibrium chemical effects, revealing that this approach avoids physical singularities, elucidates dynamic mode responses, and extends stable stellar branches to accommodate higher-mass configurations like PSR J0740+6620.
This study investigates the impact of Energy-Momentum Squared Gravity (EMSG) on neutron star properties across various equations of state, utilizing numerical solutions and observational constraints to determine how the theory's free parameter influences mass-radius relations, phase transitions, and the fundamental-mode (-mode) oscillation frequency.
This paper introduces SPARKX, an open-source Python package designed to streamline and enhance the analysis of relativistic kinematics in heavy-ion collision experiments by providing a comprehensive, multi-format toolkit that integrates with major simulation frameworks like SMASH and JETSCAPE.
Using the X-SCAPE event generator coupled with the SMASH afterburner, this study demonstrates that hadronic rescattering significantly modifies jet fragmentation observables even in small systems like collisions, highlighting the critical role of the hadronic phase in jet quenching across different collision environments.
This paper presents a global Bayesian analysis of diffractive photoproduction on proton and lead targets using a color glass condensate framework, revealing that while simultaneous description of HERA and LHC data is challenging, introducing an overall -factor significantly improves the model's ability to fit both datasets.
This study demonstrates that Energy-Momentum Squared Gravity significantly alters the curvature profiles of neutron stars and produces distinct discontinuities at hadron-quark phase transitions, offering potential observational signatures for detecting exotic core phases in modified gravity scenarios.
This paper establishes that the three-body renormalization relation in Short-Range Effective Field Theory universally follows a real Möbius transformation characterized by three regulator-dependent parameters for general separable regulators, thereby extending the understanding of the Efimov effect's RG limit cycle beyond sharp cutoffs.
