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 demonstrates that two distinct frameworks for perfect spin hydrodynamics—based on classical kinetic theory and the Wigner function—yield conserved currents with identical forms at every order of spin polarization expansion, differing only by a monotonically increasing multiplicative factor.
This paper presents the first evaluation of virtual resonance contributions to charged-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these intermediate states induce permille-level corrections to the cross sections while exhibiting expected infrared behavior.
This paper offers a pedagogical introduction to the Silver Blaze problem in QCD, which addresses the paradox of why physical observables remain unchanged below a critical chemical potential despite the chemical potential altering the Dirac operator's eigenvalues, by analyzing the behavior of functional integrals and the role of phase cancellations in gauge configurations.
This paper utilizes Bayesian thermal analysis of hadron yields from STAR Ru+Ru and Zr+Zr isobar collisions to precisely extract chemical potential differentials in the QCD phase diagram, thereby validating these collisions as a high-precision probe for four-dimensional QCD thermodynamics against lattice-QCD and Chiral Mean Field model predictions.
This paper investigates the frame dependence of QCD bound states quantized in the temporal gauge under a constant gluon field, deriving their wave functions and demonstrating the Lorentz covariance of electromagnetic form factors for states of any spin.
This paper utilizes the Phase Function Method with optimized Morse potentials derived from the GRANADA analysis to calculate exact radial neutron-proton wavefunctions and phase shifts for various uncoupled channels, demonstrating excellent agreement with high-precision Nijmegen-II results across a wide range of laboratory energies.
This paper resolves the ambiguity in mixing between nonlocal gluon and quark bilinear operators by demonstrating that dimensional regularization provides a consistent prescription for handling singularities at zero separation, ensuring agreement between coordinate and momentum space results and compatibility with lattice QCD extractions.
This paper pays tribute to the late Toshimitsu Yamazaki by highlighting his pioneering work on deeply bound pionic states and kaonic nuclei, while also presenting recent findings that confirm a deeply bound dibaryon is not excluded by hypernuclei observations but remains too short-lived to be a dark matter candidate.
This paper investigates the Dirac limit of QCD in the large limit, demonstrating that the light quark wave function remains frame-independent and that the discrete bound state spectrum of the theory corresponds to the discrete energies of a Dirac equation with a linear potential.
Through large-scale shell-model calculations, this study identifies the low-energy enhancement in the gamma-decay strength of V as a magnetic dipole phenomenon driven by constructive interference between spin and orbital components of the proton transitions.
