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 investigates whether a chiral density wave phase at large baryon chemical potential can enable QCD-induced little inflation to produce observable nano-Hz gravitational waves, but concludes that the resulting latent heat is insufficient to support a viable cosmological scenario.
This study demonstrates that r-process nucleosynthesis abundance patterns are primarily driven by local nuclear shell effects rather than bulk nuclear mass properties, indicating that future experimental and theoretical efforts should prioritize understanding these local mass variations.
This study utilizes a (1+1)D relativistic magnetohydrodynamic framework with Bjorken flow to demonstrate how time-dependent ultra-strong magnetic fields and temperature-dependent magnetic susceptibility differentially influence Quark-Gluon Plasma energy density evolution, revealing that magnetic pressure suppresses decay in ultra-relativistic fluids while enhanced coupling accelerates dissipation in conformal fluids.
This paper presents a new formalism for estimating truncation errors in the electric basis of lattice gauge theory simulations on quantum computers, leveraging Hilbert space fragmentation to demonstrate that errors decay factorially with field truncation, thereby improving previous error estimates by a factor of up to for models like the Schwinger model and pure U(1) gauge theory.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper reviews the theoretical and experimental status of the predicted sign reversal of Boer-Mulders functions between semi-inclusive deep-inelastic scattering and Drell-Yan processes, demonstrating that current data supports this reversal for proton valence quarks while highlighting future prospects for testing it in pions at the Electron-Ion Collider.
This paper combines high-energy collision data analyzed via the PHSD transport approach with cosmological and astrophysical constraints to establish comprehensive exclusion limits on the parameter space of a kinetically mixed dark photon model coupled to stable dark matter.
This paper employs a microscopic Skyrme Hartree-Fock-based folding potential model to simultaneously describe low-energy elastic scattering and calculate the astrophysical factor for the He()Be reaction, yielding a recommended zero-energy value of keV b that agrees well with experimental data.
This review paper outlines the physics prospects of proposed Super Tau-Charm Factories, highlighting their unique capabilities in high-luminosity electron-positron collisions to advance precision tests of the Standard Model, explore CP violation, study tau and charm properties, and investigate nonperturbative QCD phenomena.
This paper reformulates stellar structure equations as a dynamical system to demonstrate that the maximum mass of stellar sequences corresponds to a fixed point in the relativistic regime, a framework that explains equation-of-state-insensitive relations and suggests that the pulsar J0740+6620 likely lies near this maximum only if a strong first-order phase transition occurs just above its central density.
