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 employs a Multi Step Shell Model approach to calculate and analyze the energy levels, electric transition rates, and wavefunction similarities of the -like nuclei Te and Te, which are constructed by coupling proton and neutron phonon states above the doubly magic Sn and Sn cores.
This paper extends renormalization-group-optimized perturbative QCD to -equilibrated matter to derive a compact equation of state for massive quarks, demonstrating that specific renormalization scale parameters can yield stable pure and hybrid quark stars compatible with recent astrophysical observations like PSR J0740+6620 and GW190814.
Heavy-ion collisions serve as a crucial tool for constraining the nuclear equation-of-state at high densities, offering insights that complement multi-messenger astronomy observations of neutron stars, while future advancements in experimental precision and transport modeling are essential to further elucidate the symmetry energy and related nuclear phenomena.
Using the AMPT model for Au+Au collisions at 200 GeV, this study demonstrates that anisotropic hadronic rescattering, driven by Lorentz boost effects on decay angles, significantly suppresses reconstructed yields and induces apparent spin alignment signals ( deviations) in both production-plane and helicity frames, even in the absence of intrinsic polarization.
This paper employs a quadrupole-octupole axially symmetric model to systematically investigate the Gd isotopic chain (), revealing a smooth evolution of quadrupole deformation with a critical jump at and an inverse correlation where enhanced quadrupole collectivity coincides with the loss of octupole deformation, which is restricted to the lightest Gd nuclei.
This paper reports experimental evidence of power-law late-time decay in two fluorescent compounds, demonstrating that while the decay lifetime is universal, the specific late-time deviations depend on the detection channel, consistent with a divergent spectral density model in multichannel quantum mechanics.
This paper demonstrates that the transverse momentum spectra of charged particles in proton-proton collisions can be robustly decomposed into distinct soft and hard components that remain invariant across multiplicity classes, supporting a two-component interpretation as a viable alternative to hydrodynamical models.
This paper presents improved Monte Carlo neutrino transport simulations for binary neutron star mergers that incorporate inelastic neutrino-electron scattering and refined pair processes, revealing a 50% increase in ejected mass and significant reductions in heavy-lepton neutrino energy and luminosity without increasing computational costs.
This paper demonstrates that dark matter admixture in neutron stars can significantly reduce crust thickness and increase torsional oscillation frequencies, particularly when a "dark core" forms, offering a potential observational method to distinguish dark matter effects from microphysical uncertainties like electron screening.
This paper establishes a robust linear correlation between single- and double- hypernuclear binding energies to statistically evaluate interaction energies in heavier systems, revealing that these values are systematically larger than standard mean-field predictions and providing crucial benchmarks for future experiments.
