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 presents a unified open quantum system framework based on the Lindblad equation to describe both the suppression and thermal recombination of charmonium and bottomonium states in ultrarelativistic heavy-ion collisions undergoing Bjorken expansion.
This paper proposes a field-theoretical framework, analogous to the BEC-BCS crossover in ultracold atoms, to explain the hadron-quark crossover in dense matter by demonstrating that a tripling fluctuation effect naturally reproduces key quarkyonic features such as the speed of sound peak and baryon momentum-shell structure.
This paper establishes a self-consistent spectral framework that unifies the Ichimura-Austern-Vincent inclusive non-elastic breakup theory with the Trojan Horse Method by demonstrating that the latter's resonance-strength formula is a specific non-perturbative reduction of the former's per-pole distorted-wave Born approximation cross sections under well-defined sub-Coulomb conditions.
This study compares the longitudinal deposition of conserved quantities in the string-based SMASH and saturation-based McDipper initial condition models across a wide range of collision energies, revealing significant discrepancies in energy and baryon deposition at higher center-of-mass energies despite good agreement at lower energies.
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.
