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 challenges established views on hot QCD by demonstrating that an intermediate phase exhibits emergent chiral spin symmetry with persistent mesonic excitations, and proposes that thermal quantum field theories are fundamentally composed of non-perturbative "thermoparticles" rather than perturbative degrees of freedom.
This study demonstrates that in high-energy oxygen-oxygen collisions at 5.36 TeV, the produced QCD matter only partially reaches local equilibrium, necessitating a core-corona framework rather than a purely hydrodynamic approach to accurately describe the dynamics, particularly the incomplete chemical equilibrium observed in strange baryon yields.
Using color-spin molecular dynamics, this study reveals that neutron-star matter favors the formation of multi-quark clusters with integer baryon numbers over isolated quarks, while demonstrating that interactions between strange and light quarks significantly influence neutron-star radii, offering a potential pathway to constrain flavor-sector interactions through future observations.
This paper presents an exact flux identity derived from a complex-potential framework that partitions the absorption cross section into inner capture and peripheral loss, demonstrating that channel couplings in weakly bound nuclear reactions like Li+Bi redirect absorbed flux from peripheral breakup to fusion above the barrier, thereby identifying peripheral losses as the primary cause of complete-fusion suppression.
This study demonstrates that using transverse spherocity to classify Pb+Pb collisions into isotropic and jetty topologies provides a cleaner and more reliable method for probing the Chiral Magnetic Effect by effectively suppressing flow-driven and resonance-decay backgrounds compared to traditional flow-vector-based approaches.
The CMS experiment at the LHC reports the first observation of nuclear suppression in coherent (1S) photoproduction off heavy nuclei, measuring a nuclear gluon suppression factor of at a high energy scale of GeV and .
This paper calculates the resummed perturbative free energy of four-dimensional supersymmetric Yang-Mills theory to order in the 't Hooft coupling, demonstrating that all infrared divergences cancel, comparing different regularization schemes and Padé approximants, and showing that the theory exhibits superior convergence properties compared to QCD.
This study applies a Bayesian uncertainty quantification framework to a three-body model of the two-neutron halo nucleus C, revealing that it is bound by less than 0.35 MeV with a dominant configuration and demonstrating that its dipole strength is highly sensitive to the underlying C- interaction properties.
This paper introduces a variational neural network approach to solve the free Klein-Gordon model in the momentum-space field basis, systematically benchmarking its accuracy against exact analytic results for key observables to establish a foundation for future applications to interacting theories.
This paper proposes nucleon energy correlators as a novel, inclusive framework using azimuthal asymmetries in the target fragmentation region to linearly constrain electroweak light-quark dipole operators at the Electron-Ion Collider without requiring polarized beams or final-state hadron identification.
