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 presents non-perturbative lattice calculations of the low-lying spectrum and matrix elements of chimera baryons within a Sp(4) gauge theory, a key component of composite Higgs models, utilizing both quenched and dynamical fermion approximations.
This paper extends neural-network quantum states to solve strongly interacting few-body problems in continuous space, successfully computing Efimov states and reproducing their key physical features for systems ranging from three to six identical bosons and mass-imbalanced fermions.
This paper investigates boost-invariant spin hydrodynamics with a first-order framework, demonstrating that spin dissipation alters the temperature evolution of the expanding medium and subsequently enhances thermal dilepton production, thereby suggesting dileptons as a viable probe for spin dynamics in the quark-gluon plasma.
This paper investigates how fermionic dark matter interacting with nucleons via a vector mediator () alters the equation of state and structural properties of neutron stars, demonstrating that observational constraints on mass, radius, and tidal deformability can limit vector portal parameters while linking astrophysical findings to terrestrial dark matter searches.
This paper demonstrates that the nucleus Er exhibits rigid triaxiality with a deformation angle of rather than a prolate shape, a conclusion supported by the SU(3)-IBM framework including higher-order interactions which accurately reproduces experimental energy spectra, transition strengths, and quadrupole moments.
This study employs the Relativistic Mean Field model with NL-SH and NL3* parameters to analyze the ground-state properties and decay characteristics of Es-240-259 isotopes, revealing a shell closure at N=154 and providing insights into their structural stability and decay mechanisms.
This paper presents a constituent two-gluon model for the lowest-lying glueball states in pure Yang-Mills theory, calibrated against lattice results, which reveals that the compact scalar glueball has a radius comparable to the instanton size while the extended tensor state is shaped by a centrifugal barrier, with the framework also supporting Regge behavior for excited states.
This paper benchmarks a minimal extension of the quantum-number projected generator coordinate method (PGCM) for describing Gamow-Teller transitions and neutrinoless double-beta decay matrix elements in even-even nuclei, demonstrating its validity against exact shell-model solutions and configuration-interaction calculations in calcium and titanium isotopes.
This paper utilizes nuclear density functional theory with symmetry breaking and restoration to calculate the radiative decay properties and electromagnetic moments of the ground and isomeric states in Th, finding good agreement with experimental data while highlighting the need for improved octupole descriptions in future Skyrme functional parametrizations.
This paper reviews the application of the ab initio no-core shell model with continuum (NCSMC) approach, utilizing chiral nuclear forces to unify the description of bound and unbound states in light halo nuclei such as He, B, Be, and C, while also addressing challenges in modeling Borromean systems and presenting preliminary studies on Be and Li.
