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 surveys empirical evidence and theoretical frameworks, ranging from multifragmentation data and mean-field calculations to chiral effective field theory, regarding the first-order liquid-gas phase transition in nuclear matter and the determination of its critical point.
This paper proposes a method to compute energy-integrated neutrino cross sections directly from Euclidean responses by decomposing kinematic prefactors into moments and specific weighted integrals, thereby avoiding the need for Laplace transform inversion and enabling ab-initio calculations with controlled uncertainties.
This paper proposes a new nonet scheme for scalar mesons (, , , and ) as -wave quark-antiquark states while identifying as a glueball, supporting this classification through statistical and coalescence model calculations of their production yields in relativistic heavy ion collisions.
This paper investigates the electromagnetic structure of heavy quarkonia and the meson using a light-front quark model with variational wave functions, finding that the electromagnetic radii of and states are approximately 1.5 and 1.9 times larger than their counterparts, respectively, in agreement with lattice QCD data and other model predictions.
This paper extends the consistent- scheme within the interacting boson fermion fermion model to odd-odd nuclei, demonstrating that unpaired nucleons do not suppress critical behavior during shape phase transitions, thereby confirming that these transitions remain fundamental to the structural evolution of such systems in heavy and intermediately-heavy mass regions.
This paper employs the Gamow shell model in the coupled-channel formulation (GSMCC) with a cluster expansion to simultaneously describe the spectrum of Li and the elastic scattering reaction He(H, H)He.
This study employs the Gamow shell model with a translationally invariant Hamiltonian to investigate the behavior of continuum-coupling correlation energy for near-threshold states in Li and Be.
This paper calculates the pion valence parton distribution function using a spectral function approach with phenomenological Light-Front wave functions, revealing that the observed intermediate-x behavior and limit are driven by a highly virtual cluster carrying most of the momentum with minimal residual mass, thereby linking the PDF's peak characteristics directly to its analytic behavior at .
This paper introduces a momentum rescaling framework that explains the unexplained rise-and-fall pattern of radial flow fluctuations in the quark-gluon plasma by factorizing them into a kinematic component driven by spectral shape transitions and a dynamical component that reveals significant medium-dependent deviations in LHC and RHIC collisions.
This paper employs a covariant Vlasov approach with relativistic mean-field models to demonstrate that strong magnetic fields induce Landau quantization in proton-like modes and generate new low-lying isovector collective modes in asymmetric nuclear matter, while leaving neutron-like modes largely unaffected.
