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 introduces a new parametrization for N-point energy correlators that enables the derivation of a general factorization theorem in the back-to-back limit and the analytic determination of leading non-perturbative power corrections for arbitrary N, including non-integer values, thereby facilitating future precision extractions of the strong coupling constant.
This study resolves a long-standing discrepancy in the to transition strength of Fe by using Coulomb-excitation measurements to demonstrate that previous lifetime data were overestimated due to outdated electronic stopping power models, thereby confirming the validity of shell-model predictions.
This paper formulates a relativistic hydrodynamic theory for fluids with spin and intrinsic dilation charges, deriving constitutive relations that reveal gapped dilation excitations and scale-anomaly-induced transport effects, which reduce to microstretch fluid dynamics in the nonrelativistic limit and apply to rapidly expanding or contracting nearly conformal systems.
This paper investigates the late-time asymptotic behavior of superfluid Bjorken flow using Mueller-Israel-Stewart theory coupled to a complex scalar field, revealing that dissipative evolution leads to novel transseries solutions containing factors that encode initial data dilution and exhibit either damped fall-off or oscillations depending on the condensate relaxation rate, with potential implications for heavy-ion collision experiments.
This study utilizes the deformed relativistic Hartree-Bogoliubov theory and experimental mass data to derive the symmetry energy coefficients for Pb and Ca isotopes from two-nucleon separation energies, ultimately determining a model-independent volume symmetry energy of approximately 27.0 MeV by constraining the surface-to-volume energy ratio.
This study utilizes the deformed relativistic Hartree-Bogoliubov theory in continuum to explain the abnormal charge radii evolution in neutron-deficient gold isotopes through prolate-to-oblate shape transitions and successfully reproduces the kink structure observed in lead isotopes near the shell.
This study demonstrates that in Pb, Hg, and Ar isotopes, pairing energy and mean field energy exhibit a strong anti-symmetric correlation with nuclear deformation, indicating that these two components interact cooperatively to determine the total energy minimum.
This study investigates the impact of the intrinsic geometric structure and -clustering of the Ne nucleus on particle production in Ne-Ne collisions at 5.36 TeV, revealing that while these structural features significantly modify charged particle multiplicity, their effects on transverse momentum spectra and mean transverse momentum remain modest in central collisions within a non-hydrodynamic framework.
This paper demonstrates that cluster effective field theory, when combined with machine learning optimization techniques like Differential Evolution and Markov chain Monte Carlo, provides a reliable and systematic framework for accurately analyzing low-energy elastic -C scattering data relevant to stellar evolution and nucleosynthesis.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
