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.
Using lattice QCD with ensembles at a pion mass of approximately 292 MeV, this study determines finite-volume energies of two-nucleon systems in the and channels and extracts scattering amplitudes via Lüscher's method and the Non-Perturbative Hamiltonian framework, revealing that both the deuteron and di-neutron channels exhibit virtual state poles with binding energies of MeV and MeV, respectively.
This paper demonstrates that applying a specific non-unique coordinate transformation using experimentally derived deformation parameters to Bohr's quasi-molecular model successfully reproduces the emergence of cluster formation and characteristic shapes in light nuclei, such as B and Ne, while providing a physical interpretation of triaxiality through the superposition of multiple intrinsic configurations.
This paper investigates the parton distribution functions of kaon and heavy pseudoscalar mesons using a light-cone quark model evolved via NLO DGLAP equations, providing predictions for NLO structure functions at Electron-Ion Collider energies and Drell-Yan cross sections for the COMPASS++/AMBER experiment while demonstrating the dominance of heavy constituents in carrying momentum fractions.
This paper introduces a Flow Matching generative model that rapidly and accurately predicts final-state hadron spectra from jet-induced hydrodynamic responses in heavy-ion collisions, achieving a six-order-of-magnitude computational speedup over traditional full simulations while preserving key physical properties.
This paper introduces a relativistic Hartree-Fock framework with momentum-dependent nuclear interactions to improve the calculation of charged-current neutrino opacities for astrophysical simulations, revealing significant discrepancies and substantial shifts in medium-dependent modifications compared to commonly used relativistic mean-field models.
This paper rigorously proves that for finite-range potentials featuring an inner repulsive core and an outer attractive tail, the effective range remains strictly positive whenever the scattering length exceeds the potential's range, thereby providing a fundamental constraint on using the sign of the effective range to distinguish exotic hadron configurations.
This paper computes the gravitational form factors of pion and kaon mesons using Basis Light-Front Quantization, finding agreement with lattice QCD for the form factor while observing an enhanced magnitude for the form factor at low momentum transfer due to zero-mode effects, and subsequently derives the mesons' mass and mechanical radii along with their internal pressure and shear-force distributions.
This paper proposes and theoretically validates a new method to observe quark effects in nuclei by analyzing in-medium modified nucleon magnetic moments through bremsstrahlung spectra in proton-nucleus scattering, specifically highlighting the potential of using ratios between carbon isotopes like C and C to isolate these effects.
This study employs an \textit{ab initio} valence space in-medium similarity renormalization group method to investigate quantum entanglement measures, such as proton-neutron entanglement entropy and mutual information, revealing their critical role in characterizing the structure and correlations within the island of inversion region for neutron-rich Ne, Mg, and Si isotopes.
This paper presents the first Bayesian extraction of the trace anomaly of cold dense matter from collective flow observables in heavy-ion collisions, demonstrating a quantitative agreement with independent astrophysical constraints from neutron stars and establishing a consistent macroscopic bridge between terrestrial and cosmic dense-matter environments.
