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.
Using an extended isospin- and momentum-dependent Boltzmann-Uehling-Uhlenbeck transport model, this study demonstrates that incorporating momentum dependence in the nuclear mean field is essential for accurately reproducing STAR experimental data on proton, kaon, and production in Au+Au collisions at GeV, whereas momentum-independent models only partially describe the results.
This paper derives analytical evolution equations for two- and three-point velocity correlators in a boost-invariant relativistic fluid using effective field theory, demonstrating that the Landau frame is optimal for studying non-Gaussian fluctuations and revealing that three-point correlations exhibit nonlinear memory effects dependent on two-point dynamics, which are crucial for the search for the QCD critical point.
This paper provides a comprehensive overview of chiral symmetry and its restoration in QCD, covering fundamental theoretical concepts like spontaneous symmetry breaking and the Nambu-Goldstone theorem, exploring various effective models such as the Nambu-Jona-Lasinio and linear models, and discussing experimental signatures and implications for the equation of state in nuclear and neutron-star matter.
This paper presents the first calculation of next-to-next-to-leading order (NNLO) QCD radiative corrections for deeply virtual pion production, demonstrating that these two-loop corrections substantially improve the agreement between perturbative QCD predictions and experimental data from JLab while also refining theoretical descriptions of transverse single-spin asymmetries for future facilities like the EIC and EicC.
This article presents a vision for the emerging era of rare isotope beam science, emphasizing the critical integration of theoretical, computational, and experimental advances to explore exotic nuclei near drip lines and their connections to nuclear astrophysics.
This paper proposes using time modulation in weak nuclear decays as a probe for axion dark matter, deriving a theoretical framework to predict such variations, constraining axion parameters using existing Gran Sasso data on K and Cs, and suggesting a new electron capture measurement to extend sensitivity to higher axion masses.
This paper demonstrates that quantum-inspired deep neural networks (QDNNs) offer superior predictive accuracy and tighter uncertainties compared to classical methods for extracting Compton form factors from JLab experimental data, establishing them as an efficient tool for future multidimensional studies of hadronic structure.
This paper demonstrates that while global multiplicity fluctuations introduce a constant vertical offset in the differential radial flow observable , only the shape of this distribution (or its derivative) contains genuine physical information about radial-flow dynamics, rendering its zero-crossing point physically insignificant.
This paper demonstrates that an ultralight scalar dark matter field coupling to neutrinos can significantly amplify the rate of lepton-flavour-violating muon-to-positron conversion in nuclei, thereby enabling upcoming experiments to establish stringent new constraints on neutrino-dark matter couplings that surpass current cosmological and terrestrial limits.
This study utilizes astrophysical observations, including massive pulsar measurements, NICER data, and GW170817 tidal deformability constraints alongside perturbative QCD calculations, to significantly restrict the admissible parameter space for the equation of state of cold, dense strongly interacting matter.
