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 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.
This paper proposes a quark-meson framework incorporating temperature-dependent quark masses and anomalous magnetic moments to reconcile lattice QCD magnetic susceptibility data with theoretical models, demonstrating that quark degrees of freedom must emerge significantly below the QCD cross-over temperature (around 120 MeV) to explain the observed paramagnetism.
Using a coalescence model coupled with the MUSIC hybrid framework, this study investigates the elliptic and triangular flow of light (anti-)(hyper-)nuclei in Pb+Pb collisions at 5.36 TeV, revealing the breakdown of simple constituent scaling at high transverse momentum, the insensitivity of hypertriton flow to internal structure, and providing predictions for comparison with ALICE experimental data.
This paper presents the first calculation of tensor and axial-tensor mesons with total spin within the Covariant Spectator Theory, utilizing a refined quark-antiquark interaction kernel with momentum-dependent strong coupling to successfully describe the mass spectrum of heavy and heavy-light mesons using only eight adjustable parameters.
This paper proposes using forward-backward multiplicity asymmetry (FBMA) in uranium-uranium collisions as a robust control parameter to effectively disentangle the Chiral Magnetic Effect signal from flow-induced backgrounds by leveraging the correlation between FBMA and initial-state geometry while largely decoupling it from magnetic field correlations.
This paper demonstrates that the universality of the shear viscosity to entropy density ratio in Unruh radiation is fundamentally linked to causality, establishes a saturation of the bulk viscosity bound, and derives a novel sum rule for spectral densities that connects thermal isotropy in Rindler space to the validity of Pascal's law.
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.
