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 demonstrates that quarkyonic matter suppresses neutron-star -mode frequencies by nearly an order of magnitude and reverses their mass dependence compared to standard nucleonic models, due to the strong-interaction-maintained chemical equilibrium that eliminates quark thermodynamic freedom and drastically reduces core stratification.
This study employs a consistent open-quantum-system transport framework to demonstrate that the same microscopic transport coefficients successfully describe bottomonium suppression across Pb-Pb, O-O, and Ne-Ne collisions, supporting a common origin for these effects in deconfined matter despite significant variations in system size.
This study demonstrates that simultaneously incorporating in-medium modifications of nucleon-nucleon inelastic cross sections and short-range-correlation-induced high-momentum tails into the UrQMD transport model successfully reproduces experimental pion yields and ratios in intermediate-energy heavy-ion collisions, thereby highlighting the critical role of both factors in accurately modeling pion production.
This study presents the first fully general relativistic investigation of non-radial -mode oscillations in neutron stars with dark energy cores, revealing that such cores soften the equation of state and modify oscillation properties while remaining consistent with current pulsar and gravitational wave observations and predicting detectable signals for future third-generation detectors.
This paper introduces a novel projected shell model method, leveraging physical guidance and the Pfaffian algorithm to calculate nuclear level densities in heavy deformed nuclei, with results from Dy suggesting a need to revise current understandings of structural behavior in the pair-breaking region.
This paper establishes a threshold resummation framework for computing large- parton distribution functions via large-momentum effective theory by factorizing the matching coefficient into a space-like jet function and heavy-light Sudakov form factors, thereby enabling direct lattice QCD calculations of these critical distributions with NNLO consistency.
This paper investigates large- parton distribution functions within large momentum effective theory by factorizing the matching coefficient into hard and soft components to resum threshold double logarithms and leading renormalons, demonstrating that perturbative matching remains reliable when both active and spectator quark momenta significantly exceed the QCD scale.
This paper presents a theoretical study using the SHELL transport model showing that the suppression of high relative transverse momentum in groomed jet substructures in heavy-ion collisions arises from partonic energy loss and selection bias, while the broadening of the groomed jet radius in photon-tagged jets provides direct evidence of medium-induced gluon radiation effects.
This paper proposes a novel method to precisely determine the fourth moment of the 208Pb nuclear charge-density distribution using low-momentum-transfer elastic electron scattering.
This paper proposes using polarized positron capture on deuterium at Jefferson Lab, analyzed via a relativistic momentum-space formalism, to precisely determine the low- behavior of the nucleon axial form factor and reduce systematic uncertainties in neutrino-oscillation studies.
