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.

Benchmarking neutrino-nucleus quasielastic scattering model predictions against a missing energy profile obtained using a monoenergetic neutrino beam

This paper benchmarks three exclusive nuclear ground-state shell models implemented in the NEUT neutrino event generator against recent JSNS2^2 measurements of missing energy from a monoenergetic neutrino beam, finding that spectral function models outperform relativistic mean field models and that accounting for missing energy thresholds allows all tested nuclear models to be statistically accepted.

Neutron star structure and nuclear matter properties from a general Walecka-type model with Bayesian analysis

This paper employs a Bayesian analysis of a general Walecka-type model to demonstrate that pure hadronic matter, through specific meson mixing, can naturally generate a peak in sound velocity—a feature often linked to phase transitions—thereby offering a new microscopic explanation for the structure of both medium and massive neutron stars without invoking exotic phases.

Neural network enhanced Bayesian global analysis of relativistic heavy ion collisions

This paper presents a novel deep convolutional neural network-enhanced Bayesian global analysis of relativistic heavy-ion collisions that significantly reduces computational costs to constrain QCD matter properties, revealing a temperature-dependent shear viscosity plateau and non-zero bulk viscosity while confirming that hydrodynamic freeze-out occurs at the expected applicability limit.

(2+2)D Collective Model based on a relativistic Boltzmann equation in the Isotropization Time Approximation: CoMBolt-ITA

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.

Probing the three-body force in hadronic systems with specific charge parity

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 DˉsDK\bar{D}_sDK system, they are crucial for determining whether the Dˉ∗Dη\bar{D}^*D\eta system forms a bound state.

Binding Energy of Muonic Beryllium: Perturbative versus All--Order Calculations

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 9^9Be charge radius and bridging theoretical methodologies between light and heavy muonic systems.

Toward scalable quantum computations of atomic nuclei

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.
