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 establishes that the three-body renormalization relation in Short-Range Effective Field Theory universally follows a real Möbius transformation characterized by three regulator-dependent parameters for general separable regulators, thereby extending the understanding of the Efimov effect's RG limit cycle beyond sharp cutoffs.
This study investigates how variations in symmetry energy within nucleonic and hyperonic equations of state affect the global properties and universal relations of hot, isentropic compact stars in both static and maximally rotating configurations, demonstrating that these universal relations remain robust across diverse conditions relevant to binary neutron star mergers and proto-neutron stars.
This study investigates the mass spectra and Mott transitions of neutral mesons () within a three-flavor Polyakov-extended Nambu-Jona-Lasino model at finite temperature and magnetic field, revealing how gluon effects and inverse magnetic catalysis influence chiral symmetry restoration, flavor mixing, and the temperature-dependent behavior of meson masses.
This paper investigates the decay as a probe for vorticity and spin alignment in heavy-ion collisions by deriving the general angular distribution of pions via interaction Lagrangian and helicity formalism, and subsequently calculating spin density matrix elements under local thermal equilibrium and blast wave models across different centrality classes.
This paper introduces finite Gaussian assistance protocols and a multimode conic metric framework to optimize spacelike vacuum entanglement, yielding the highest known lower bound for Gaussian entanglement of assistance and the lowest known upper bound for Gaussian entanglement of formation in free scalar fields.
This paper demonstrates that two distinct frameworks for perfect spin hydrodynamics—based on classical kinetic theory and the Wigner function—yield conserved currents with identical forms at every order of spin polarization expansion, differing only by a monotonically increasing multiplicative factor.
This paper presents the first evaluation of virtual resonance contributions to charged-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these intermediate states induce permille-level corrections to the cross sections while exhibiting expected infrared behavior.
This paper offers a pedagogical introduction to the Silver Blaze problem in QCD, which addresses the paradox of why physical observables remain unchanged below a critical chemical potential despite the chemical potential altering the Dirac operator's eigenvalues, by analyzing the behavior of functional integrals and the role of phase cancellations in gauge configurations.
This paper utilizes Bayesian thermal analysis of hadron yields from STAR Ru+Ru and Zr+Zr isobar collisions to precisely extract chemical potential differentials in the QCD phase diagram, thereby validating these collisions as a high-precision probe for four-dimensional QCD thermodynamics against lattice-QCD and Chiral Mean Field model predictions.
This paper investigates the frame dependence of QCD bound states quantized in the temporal gauge under a constant gluon field, deriving their wave functions and demonstrating the Lorentz covariance of electromagnetic form factors for states of any spin.
