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 proposes a discovery-grade framework for detecting sub-MeV dark matter by searching for correlated "satellite-line combs"—multiple weak -ray lines shifted by a common energy offset below known neutron-capture transitions—using high-resolution HPGe detectors to suppress nuclear and instrumental backgrounds.
This paper computes non-eikonal corrections to dijet production in deep inelastic scattering off a nucleus, deriving all-order expressions in terms of path integrals and demonstrating that next-to-eikonal corrections vanish under the harmonic oscillator approximation for target averages.
This paper presents CoMBolt-ITA, a new (2+2)D collective model based on the relativistic Boltzmann equation in the isotropization time approximation that successfully couples pre-equilibrium dynamics with hydrodynamics to simulate quark-gluon plasma evolution, demonstrating strong consistency with standard hydrodynamic and hybrid models for small shear viscosity while revealing significant discrepancies and nontrivial thermalization effects for larger viscosity values.
This paper proposes that three-body forces are definitively necessary in specific three-body hadronic systems with certain charge parities, demonstrating through contact-range potential calculations that while these forces play a minor role in the system, they are crucial for determining whether the system forms a bound state.
This paper demonstrates that both perturbative and all-order relativistic approaches yield consistent ground-state binding energies for muonic beryllium to within one part per million, thereby providing a precise parametrization for extracting the Be charge radius and bridging theoretical methodologies between light and heavy muonic systems.
This paper demonstrates that quantum simulations of pionless effective field theory using local Hamiltonians and adaptive unitary coupled cluster ansätze can efficiently and scalably compute accurate ground-state energies for light nuclei like the deuteron and helium-3, offering a promising approach for preparing initial states in larger-scale quantum nuclear computations.
This paper presents a method to construct a smooth QCD equation of state that incorporates a critical point and a first-order phase transition line terminating at it, while ensuring consistency with lattice QCD results, experimental heavy-ion collision data, and the expected 3D Ising universality class critical behavior.
This paper introduces "resolution refinement," an efficient method for bootstrapping quantum eigenstate preparation by adiabatically evolving states from low-resolution to high-resolution Hamiltonians, achieving favorable scaling with system size by preserving the structure of low-energy eigenstates.
Using heavy-nucleus effective field theory, this paper derives a universal "double-weak Sirlin function" for two-neutrino double-beta decay that significantly distorts electron energy and angular spectra, necessitating the inclusion of these radiative corrections in high-precision Standard Model tests and nuclear structure extractions.
This paper proposes a method to constrain proton multiplicity cumulants in heavy-ion collisions by leveraging Pade-resummed lattice QCD data on the Lee-Yang singularity structure, revealing four distinct scenarios for critical point signatures that depend on the critical point's location and the slope of the chiral crossover curve.
