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 extends the quark mean-field model to finite temperatures to systematically analyze the thermodynamic properties of nuclear matter relevant to neutron-star mergers, providing accurate analytical fits for the thermal index that can be directly implemented in merger simulations to assess the impact of quark-structure-based descriptions on post-merger dynamics.
This paper proposes an efficient method using the quasiparticle finite amplitude method to exactly compute adiabatic time-dependent Hartree-Fock-Bogoliubov collective inertias for fission, demonstrating that while the resulting behavior aligns with exact and non-perturbative approaches, it significantly differs from standard perturbative calculations and is largely scaled by factors related to the effective mass of the energy density functional.
This paper presents a direct three-dimensional femtoscopic analysis of pion emission sources in EPOS4 Au+Au collisions across the RHIC Beam Energy Scan range, utilizing Fast Fourier Transforms to extract Lévy parameters and reduce projection biases while comparing out-side observables with UrQMD calculations to explore QCD phase diagram signatures.
This paper utilizes a hybrid transport-hydrodynamics model to predict that dijet hadrochemistry in heavy-ion collisions serves as a novel tomographic probe, revealing enhanced hadron ratios and a diffusion wake-induced depletion that confirms jet-induced medium excitation.
This paper introduces octupole-constrained coupled-cluster theory to compute negative-parity rotational bands in deformed nuclei, demonstrating through Ne calculations that while positive-parity band energies are robust, negative-parity band energies are more sensitive to the constrained octupole moment and reference state.
The nCTEQ collaboration presents nCTEQ26, a new set of nuclear parton distribution functions derived from a global analysis incorporating the largest selection of experimental data to date—including DIS, Drell-Yan, and collider measurements—alongside an advanced parametrization and data-driven approach to determine uncertainties and validate consistency.
This paper demonstrates that neural networks trained on a small set of hybrid heavy-ion collision events can accurately predict final-state observables like multiplicity and mean transverse momentum, enabling the efficient generation of millions of simulated events to precisely define centrality and analyze flow correlations with significantly reduced computational cost.
This study presents the first *ab initio* computation of low-energy electric dipole (E1) strength for nickel isotopes using the Lorentz integral transform coupled-cluster method, demonstrating that this theoretically derived strength significantly enhances neutron capture rates for neutron-rich nuclei relevant to r-process nucleosynthesis.
This paper computes the structural properties and long-term evolution of static and rotating neutron stars by employing a finite-temperature, beta-stable hadronic equation of state that incorporates hyperons and neutrino trapping, ensuring consistency with observed massive pulsars and gravitational wave tidal deformability constraints.
This study evaluates the weak Gamow-Teller responses for low-lying states in by combining experimental electron capture rates, corrected charge exchange reaction data, and shell model calculations, revealing that excited state contributions amount to approximately 4.2% of the ground state response and confirming that the Ga anomaly cannot be explained by uncertainties in these nuclear responses.
