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.
The authors propose a new baryon deposition model incorporating baryon junctions and directed diffusion within a relativistic hydrodynamic framework, which successfully reproduces the observed double sign change in the directed flow slopes of net protons and net lambdas in Au+Au collisions at 7.7–200 GeV, thereby establishing a crucial noncritical baseline for the search for the QCD critical point.
This paper introduces PDG2021+, an updated and transport-ready hadron list based on the 2021 Particle Data Booklet for heavy-ion collision simulations, and validates its impact on key observables like the pion mean transverse momentum while quantifying systematic uncertainties arising from decay modeling approximations.
This study demonstrates that the non-locality of the absorptive optical potential in neutron elastic scattering cannot be described by a single universal constant, but instead requires a nucleus-, energy-, and radially-dependent function derived from self-consistent Skyrme-based particle-vibration coupling calculations.
This paper presents a fully covariant Quantum-Molecular Dynamics framework for relativistic N-body systems interacting via scalar and vector potentials, deriving exact equations of motion to resolve fundamental issues regarding time constraints, non-relativistic limits, and frame independence while offering new insights through scattering analyses.
This paper investigates the relativistic 3D weak-neutral axial-vector and spin distributions in nucleons, demonstrating that the conventional axial radius is physically meaningless while defining a genuine 3D spin radius dependent on the induced pseudoscalar form factor, and provides corresponding cross-section formulas to guide future neutrino-scattering experiments.
This paper presents a comprehensive lattice QCD study using RBC/UKQCD ensembles to determine the masses, decay constants, and compositeness parameters of positive- and negative-parity charm-strange and bottom-strange mesons, providing the first lattice results for and and confirming that the positive-parity states are predominantly molecular in nature.
This paper introduces a qubit-qutrit quantum tomography technique to certify entanglement in and systems despite incomplete density matrix data, thereby providing a novel probe of nonperturbative QCD hadronization and spin evolution.
This paper demonstrates that incorporating physics-based theoretical structures into the mean functions and kernels of Gaussian Process Regression significantly enhances interpolation accuracy, uncertainty calibration, and extrapolation reliability for nuclear physics problems compared to agnostic baselines.
This review presents a unified two-step method of symmetry breaking and restoration to describe universal strongly correlated phenomena, such as electron crystallization and rotating molecules, across diverse finite systems including quantum dots, ultracold Bose gases, and traditional nuclear and chemical fields.
Using Bayesian inference on multimessenger data and a physics-agnostic equation of state, this study favors a "two-family" scenario where neutron stars and strange quark stars coexist, identifying PSR J0740+6620 as a quark star and providing astrophysical support for the absolute stability of strange quark matter.
