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.
Using Bayesian analysis to combine relativistic mean-field models for hadronic matter with a vector-MIT bag model for quark matter, this study demonstrates that astronomical mass and radius observations support a phase transition to deconfined quark matter at densities below , implying the existence of hybrid neutron stars with large quark cores.
This paper presents a combined analysis of electron and proton scattering data on Zr and Mo, validated by quasiparticle-phonon model calculations, to identify mixed-symmetry states through a characteristic sign change in proton-neutron transition densities and to elucidate the role of giant resonance coupling in generating nuclear collectivity.
This review article presents an overview of dileptons as penetrating probes that, by escaping the fireball without final-state interactions, provide a space-time-evolution weighted average of the properties of hot and dense QCD matter created in heavy-ion collisions.
This study utilizes Bayesian inference on NICER mass-radius data to demonstrate that while dark energy cores significantly alter and can be constrained by neutron star observations, asymmetric dark matter cores remain observationally indistinguishable from purely baryonic stars for mass fractions up to 5%, implying that mass-radius measurements alone are insufficient to detect the latter.
This paper develops a thermodynamically consistent equation of state for hot strange quark matter incorporating perturbative QCD corrections up to and finite-temperature effects, demonstrating that such configurations are absolutely stable and can support compact stars with masses exceeding in agreement with current astrophysical observations.
This paper revises the calculation of the -box correction using a finite-mass approach to eliminate ambiguous effective quark-mass prescriptions, revealing a significant shift in electron-quark couplings extracted from Jefferson Lab PVDIS data that has important implications for precision electroweak tests.
This paper investigates gluon saturation effects in semi-inclusive deep inelastic scattering within the Color Glass Condensate framework, validating the model against HERA data and predicting significant nuclear suppression at the future Electron-Ion Collider to provide complementary constraints on nonlinear QCD dynamics.
This paper investigates accelerated gluodynamics via lattice simulations in Rindler coordinates to derive a renormalization prescription for the Polyakov loop and compares the resulting static quark properties with a non-accelerated approximation based on the Tolman-Ehrenfest law, finding good agreement near the critical temperature but deviations at higher temperatures likely due to corrections in the Rindler framework.
This paper presents an \textit{ab initio} study using chiral forces and the in-medium similarity renormalization group to successfully describe the emergence and subsequent collapse of enhanced quadrupole collectivity in nuclei near , specifically capturing the strong deformation in Zr and its reduction in heavier isotopes without empirical effective charges.
This review synthesizes how neutron skins influence particle emission and collective dynamics across heavy-ion collision energies, linking these effects to the symmetry energy, nuclear structure, and astrophysical phenomena while outlining future experimental and theoretical pathways for constraining these fundamental properties.
