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 addresses the asymptotic divergence of the axial vector propagator in the thermal AdS/QCD soft-wall model by implementing a momentum-dependent cutoff via an interior constraint approach, thereby enabling the successful calculation of electromagnetic and axial vector form factors for the transition that align moderately well with experimental and theoretical benchmarks.
This paper introduces the CoMBolt-RTA framework to simulate nonconformal kinetic theory with massive quasiparticles, successfully tuning the model to ALICE and ATLAS data on oxygen-oxygen collisions to suggest that while central OO collisions remain fluid-like, smaller helium-helium systems offer a promising avenue for studying the transition to particle-like dynamics.
This paper demonstrates that Coulomb breakup of the clustered nucleus is dominated by nuclear interactions and complicated by strong Coulomb-nuclear interferences and higher-order effects, rendering it an unreliable method for extracting the low-energy radiative capture cross section and highlighting the need for alternative indirect techniques like electron-induced dissociation.
This paper introduces UrQMD-Agent, an LLM-assisted framework that integrates large language models with deterministic scientific tools to perform microscopic transport studies, demonstrating its capability to trace and analyze negative proton azimuthal correlations in Au+Au collisions by revealing their origin in decay-fed proton pairs.
This paper investigates the global spin polarization of , , and hyperons in Au+Au collisions at RHIC BES-II energies using a viscous hydrodynamic framework, revealing that while polarization is systematically larger due to its spin, it remains below experimental measurements, suggesting potential contributions from additional mechanisms like intra-quark spin correlations.
This paper establishes the existence of linearly stable and causal BDNK hydrodynamic frames for arbitrary equations of state and transport coefficients by employing Routh-Hurwitz simplification and telegrapher factorization to provide concrete examples, map neutral-to-charged fluid frames, and introduce an AI protocol for discovering such frames in any hydrodynamic theory.
This dissertation establishes a scalable framework for digitally simulating real-time dynamics in 1+1-dimensional SU(2) lattice gauge theory and models on IBM quantum hardware, utilizing physics-informed circuits and Sequency Hierarchy Truncation to overcome resource limitations while validating results against classical benchmarks.
This paper utilizes the Bohr-Mottelson Hamiltonian with a sixth-order anharmonic oscillator potential to demonstrate that the anomaly and low-lying states of Zr arise from a triple shape coexistence scenario involving spherical, axially-symmetric deformed, and -unstable triaxial configurations.
This paper extends a full-kinematic background-field construction to quark TMDPDFs, introducing the MSTT scheme and a rapidity-only scheme that unify the description of large- and small- dynamics by simultaneously recovering CSS, DGLAP, and small- double logarithmic evolutions within a single framework.
This paper presents a comprehensive calculation of radiative corrections to two-neutrino and neutrinoless double- decay using heavy-nucleus effective field theory, revealing that neglecting these effects—particularly real-photon emission and a universal double-weak Sirlin function—significantly biases experimental analyses and increases the neutrinoless decay rate by approximately 5%.
