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 study investigates the impact of -clustering on nucleonic correlations in relativistic light ion collisions by extracting and comparing structural parameters from various *ab initio* models and density functions, revealing distinct geometric configurations and validating perturbative calculations against Monte Carlo simulations for both symmetric and asymmetric collision systems.
This paper establishes that the two-dimensional Fourier transform of generalized parton distributions encodes distinct impact-parameter densities and parton-nucleon correlations depending on skewness, leading to universal rapidity-modified angular momentum identities and providing leading-twist GPD predictions validated by lattice data and applicable to future experiments at Jefferson Lab and the Electron Ion Collider.
This paper presents an analytic string-based framework for nucleon axial and helicity-flip generalized parton distributions that satisfies fundamental theoretical constraints, reproduces existing lattice QCD moments, and provides testable predictions for sea quark and gluon polarized moments at future facilities like Jefferson Lab and the EIC.
This study employs a stochastic approach within the extended quantum molecular dynamics model to demonstrate that the peak position and width of the giant dipole resonance in Pb are highly sensitive to the symmetry energy and in-medium nucleon-nucleon cross sections, thereby offering a pathway to constrain the nuclear equation of state and confirming that a significant reduction of free cross sections in the medium is necessary to accurately reproduce experimental data.
This paper demonstrates that a modified Double Logarithmic Approximation incorporating energy conservation accurately describes the inclusive charged-particle multiplicity distributions of quark- and gluon-initiated jets in 13 TeV $pp$ collisions, showing consistency with both ATLAS experimental data and PYTHIA simulations.
This study establishes an empirical relation between the binding energy of compact stars and the frequencies of their non-radial and oscillation modes for hadronic matter, while demonstrating that hybrid equations of state with sharp phase transitions cause deviations from this quasi-universal correlation.
Using the Skyrme particle-vibration coupling model, this study investigates the -decay of the pygmy dipole resonance in Pb to the low-lying state, revealing its predominantly isoscalar character and quantifying the non-negligible yet smaller contribution of complex 1p-1h configurations coupled to the phonon compared to the giant dipole and quadrupole resonances.
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.
Using an improved Multi-Phase Transport model, this study demonstrates that the nuclear geometry and potential alpha clustering in O significantly influence anisotropic flows in O+O collisions at GeV, with the model successfully reproducing STAR data and establishing a baseline for future nuclear-structure investigations.
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.
