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.

Resummed azimuthal decorrelation and transverse momentum imbalance of dijets at the LHC

This paper presents a theoretical study of azimuthal decorrelation and transverse momentum imbalance in LHC dijet production using the recoil-free winner-take-all scheme, deriving factorization formulae in soft-collinear effective theory to perform high-precision resummation of global and non-global logarithms while demonstrating the observables' robustness against non-perturbative effects.

Probing Neutron Skins with KDAR Neutrinos: From Coherent to Diffractive Elastic Neutrino--Nucleus Scattering

This paper demonstrates that kaon-decay-at-rest (KDAR) neutrinos enable coherent elastic neutrino-nucleus scattering measurements to extend beyond the strict coherent limit into the diffractive regime, offering a competitive and complementary method to electron scattering for precisely probing neutron skin thickness in various nuclei.

Spatial confinement-deconfinement transition in accelerated gluodynamics within lattice simulation

This lattice simulation study demonstrates that weak acceleration in gluodynamics transforms the standard finite-temperature confinement-deconfinement phase transition into a spatial crossover, allowing coexisting phases that follow the Tolman-Ehrenfest law and suggesting similar phenomena may occur near black hole horizons.

Quantum design in study of pycnonuclear reactions in compact stars and new quasibound states

This paper applies a generalized quantum mechanical formalism of multiple internal reflections to pycnonuclear reactions in compact stars, revealing that a complete analysis of quantum fluxes reduces reaction rates by 1.8 times and highlights the significance of new, more probable quasibound states over zero-point vibration states, thereby necessitating a revision of nuclear reaction rate estimations in stellar environments.

Nuclear cluster structure effect in 16^{16}O+16^{16}O collisions at the top RHIC energy

Using an improved Multi-Phase Transport model, this study demonstrates that the nuclear geometry and potential alpha clustering in 16^{16}O significantly influence anisotropic flows in O+O collisions at sNN=200\sqrt{s_{\rm NN}} = 200 GeV, with the model successfully reproducing STAR data and establishing a baseline for future nuclear-structure investigations.

Helium as an Indicator of the Neutron-Star Merger Remnant Lifetime and its Potential for Equation of State Constraints

By analyzing helium abundance constraints in the kilonova AT2017gfo, this study infers that the binary neutron star merger remnant collapsed into a black hole within 20–30 ms, thereby ruling out numerous nuclear equation of state models and establishing tight upper limits on neutron star radii and maximum mass.
