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 refines theoretical predictions for light-by-light scattering by improving two-loop helicity amplitudes with asymptotic expansions and Coulomb resummation, providing state-of-the-art Standard Model cross-section calculations and a new Monte Carlo event generator named LbLatNLO.
This paper introduces an improved, composition-dependent nuclear metamodel for neutron star equations of state that enforces causality at high densities to reduce discarded models and enable Bayesian inference of complex composition-dependent properties like the dUrca threshold and g-mode stability.
This paper investigates the space-time evolution of fluid acceleration in heavy-ion collisions using AMPT and UrQMD models, revealing that peak proper accelerations reach hundreds of MeV with distinct transverse and longitudinal behaviors that may significantly impact QGP physics through effects like the Unruh phenomenon and spin polarization.
This paper presents continuum-estimated (2+1)-flavor lattice QCD results demonstrating that the baryon-electric charge correlation serves as a sensitive magnetometer for strong magnetic fields, while also mapping the equation of state up to and constructing detector-compatible observables to bridge theoretical predictions with experimental heavy-ion collision data.
Using the parity doublet model, this paper demonstrates that gravitational waves from the nuclear liquid-gas phase transition in QCD could produce detectable signals in the millihertz to nanohertz bands, whereas those from the chiral phase transition are too weak to be observed, thereby linking the chiral invariant mass to potential gravitational wave signatures of nucleon mass origins.
This paper presents a rigorous construction and uniqueness proof for the matrix Green's function of coupled radial Schrödinger equations with symmetric potentials, demonstrating its diagonal Wronskian structure and illustrating its application in capturing multistep excitation pathways within the continuum-discretized coupled-channels framework.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper demonstrates that Bose polarons immersed in a Bose-Einstein condensate can exhibit topological properties, including emergent Weyl nodes, nonzero Berry curvature, and chiral anomaly, driven solely by interspecies -wave Feshbach coupling without the need for spin degrees of freedom or spin-orbit coupling.
Using the Bethe-Salpeter formalism within the impulse approximation, this paper computes the isospin-breaking baryonic form factors for pions and kaons, yielding a baryonic radius of 0.043(2) fm for the pion that aligns with dispersive benchmarks and predicting larger radii of approximately 0.26 fm for kaons that are compatible with chiral QCD models.
