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 calculates the primordial deuterium abundance using a consistent potential-model approach for and reactions based on the Malfliet-Tjon interaction, yielding a ratio of that aligns well with observational data from metal-poor damped Lyman- systems.
By integrating uncertainty-quantified nuclear densities from the Fayans energy density functional with a modernized Glauber reaction framework, this study reanalyzes calcium isotopic interaction cross sections to refute earlier claims of dramatic neutron swelling while establishing a robust methodology for extracting neutron radii across the nuclear chart.
This paper proposes using the Artru-Collins asymmetry in dihadron fragmentation from -wave bottomonium () decays as a direct and unambiguous probe of the color-octet mechanism, offering a novel method to extract the ratio of color-octet to color-singlet matrix elements and resolve discrepancies between lattice calculations and phenomenological determinations using Belle II data.
This paper proposes novel collider methods utilizing azimuthal asymmetries of dihadron production to uniquely probe light-quark dipole moments with linear sensitivity, enabling the disentanglement of up- and down-quark contributions, separation of photon and weak boson effects, and simultaneous determination of real and imaginary parts to significantly strengthen constraints on potential CP-violating new physics.
This paper investigates the thermodynamics and structural properties of isentropic hybrid stars using a Nambu-Jona-Lasinio model for quark matter and a covariant density functional for hadronic matter, revealing that neutrino trapping significantly alters particle composition, delays the onset of deconfinement to higher densities, and leads to hybrid stars with larger radii and slightly higher maximum masses compared to their cold, neutrino-free counterparts.
This study demonstrates that total reaction and elastic scattering cross sections serve as effective probes for identifying the spin-parity and particle-hole configurations of nuclei in the island of inversion by correlating them with specific nuclear density profiles predicted via antisymmetrized molecular dynamics and the Glauber model.
Using the constituent quark potential model combined with the Gaussian expansion and complex scaling methods, this study systematically investigates S-wave singly heavy tetraquark systems with multiple strange quarks, finding no bound states but identifying several compact resonances in the charm and bottom sectors that decay into specific meson pairs and serve as targets for future experimental searches.
This paper presents a new implementation of nuclear reaction networks within the general-relativistic radiation magnetohydrodynamics code \texttt{Gmunu}, validating its accuracy through benchmarks and demonstrating its capability to simulate core-collapse supernovae where explosive burning significantly influences shock dynamics and ejecta composition.
This paper introduces a novel "charge transfer" friction term within the MUFFIN multi-fluid model for heavy-ion collisions, demonstrating that this approach offers a more consistent description of momentum-separated fluids and improved agreement with experimental data compared to existing methods.
This paper proposes analyzing heavy quark photoproduction associated with a leading neutron in proton-proton and proton-lead collisions at the LHC as a feasible method to probe the pion gluon distribution at small Bjorken- values, a kinematical range not previously covered by experiments.
