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.
By applying the BK equation to model gluon occupancy and entropy, this study demonstrates that while protons remain below the unitarity bound, heavy nuclei reach the "saturon" limit at small , identifying nuclei as the optimal environment for observing this high-occupancy QCD phenomenon.
This paper proposes that ultra-peripheral ion collisions generate entangled multi-particle states through shared photon polarization, leading to distinct azimuthal angular correlations that differ significantly between classical and quantum predictions and offer new avenues for testing multi-particle entanglement.
This paper demonstrates that background rotation catalyzes the chiral magnetovortical instability by splitting Alfvén waves into magneto-Coriolis modes, one of which becomes unstable even under weak chiral vortical effects, potentially enabling new dynamo mechanisms in rotating chiral plasmas.
This study presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using boosted correlators in the Coulomb gauge, demonstrating that the method yields results compatible with global analyses for valence-quark distributions while highlighting the need to address excited-state contamination in full-quark-channel extractions.
This paper critically reexamines gauge-space rotations in atomic nuclei by demonstrating that standard moments of inertia for like-nucleon pairing are dominated by macroscopic effects which, when removed, reveal a negative inertia driven by Pauli blocking, while simultaneously identifying -type correlations as a genuine collective quartetting mode.
This paper reviews the theoretical framework and experimental evidence for the partial conservation of seniority in semi-magic nuclei, highlighting how specific states in high- orbitals (particularly ) remain solvable and unmixed despite the expected breakdown of seniority symmetry.
Using leading-order chiral perturbation theory, this paper maps the low-energy QCD phase diagram under magnetic fields with baryon and isospin chemical potentials, identifying various exotic phases including a chiral soliton lattice and a hybrid vortex phase that may be relevant to neutron stars at magnetic fields around G.
This paper develops a new resonating group method formalism for baryon-baryon interactions that accounts for unequal oscillator frequencies arising from distinct quantum numbers, and applies this consistent framework to the system within a chiral SU(3) quark model to demonstrate its advantages over traditional approaches.
This study demonstrates that while spin polarization has a minimal effect on the squared speed of sound in noncentral O+O collisions, it significantly alters transport coefficients like shear and bulk viscosity, introducing a nonmonotonic dependence on collision energy that suggests spin polarization is a valuable probe for constraining the QCD equation of state.
This study utilizes the Jet AA Microscopic Transport Model to demonstrate that -clustering in nuclei enhances geometric compactness and radial observables like proton mean transverse momentum, as well as flow magnitudes at high participant numbers, thereby offering complementary probes for investigating nuclear structure in low-energy collisions at CSR and HIAF energies.
