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 utilizes Born-Oppenheimer Effective Field Theory and lattice QCD calculations to demonstrate that the near-degeneracy and specific decay patterns of the hidden-bottom tetraquarks and arise from the degeneracy of their underlying light degrees of freedom, identified as and adjoint mesons.
This paper presents a systematic framework for constructing covariance and correlation matrices in charged particle activation experiments by explicitly calculating both statistical and systematic uncertainties through sensitivity coefficients and parameter propagation, thereby demonstrating the critical importance of accounting for correlated uncertainties in the interpretation and comparison of experimental cross-section data.
This paper investigates whether a chiral density wave phase at large baryon chemical potential can enable QCD-induced little inflation to produce observable nano-Hz gravitational waves, but concludes that the resulting latent heat is insufficient to support a viable cosmological scenario.
This paper establishes an explicit operator-level bridge between the shock-wave formalism and non-local light-cone expansion by demonstrating that first sub-eikonal corrections in deep-inelastic scattering reconstruct standard quark distributions at finite and deriving their high-energy evolution equations, which recover the Kirschner-Lipatov exponent with full finite- color factors under symmetric double-logarithmic conditions.
This paper presents a comparative study of fragment production in Pb+Ca reactions at 50 and 100 AMeV using DJBUU and SQMD transport codes, revealing generally similar outcomes but highlighting specific discrepancies at 100 AMeV for central collisions attributed to differences in the equation of state and model stability.
This paper establishes species-resolved azimuthal anisotropy scaling functions across a wide range of beam energies to quantitatively separate viscous and hadronic effects, revealing a non-monotonic viscosity behavior near the QCD critical region and providing strong evidence for baryon junction-driven net-baryon transport at finite baryon chemical potential.
This paper applies finite-size scaling to net-baryon cumulant ratios from Au+Au collisions across the Beam Energy Scan Phase I range, revealing a universal collapse consistent with 3D Ising critical behavior and pinpointing the QCD critical end point at approximately GeV ( MeV, MeV).
This study demonstrates that r-process nucleosynthesis abundance patterns are primarily driven by local nuclear shell effects rather than bulk nuclear mass properties, indicating that future experimental and theoretical efforts should prioritize understanding these local mass variations.
This paper investigates how the nuclear symmetry energy and its density slope influence neutron driplines and neutron star properties by employing a semi-classical liquid drop model and energy density functionals constrained by chiral effective field theory to explore correlations between macroscopic observables and microscopic nuclear characteristics.
This study utilizes a (1+1)D relativistic magnetohydrodynamic framework with Bjorken flow to demonstrate how time-dependent ultra-strong magnetic fields and temperature-dependent magnetic susceptibility differentially influence Quark-Gluon Plasma energy density evolution, revealing that magnetic pressure suppresses decay in ultra-relativistic fluids while enhanced coupling accelerates dissipation in conformal fluids.
