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 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.
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.
