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.

Complete NLO BFKL impact factors for quarkonium hadroproduction in NRQCD: the case of ${}^1S_0^{[1]}$ , ${}^1S_0^{[8]}$ , and ${}^3S_1^{[8]}$ states

This paper presents the first complete next-to-leading-order calculation of BFKL impact factors for the hadroproduction of specific NRQCD quarkonium states by combining virtual corrections with real-emission contributions, demonstrating the cancellation of soft divergences and the compatibility of surviving collinear singularities with factorization to enable future next-to-leading-logarithmic precision studies.

Non-perturbative flavor asymmetry in the nucleon and deuteron: The light-front Hamiltonian effective field theory approach

This paper employs Light-Front Hamiltonian Effective Field Theory with non-perturbative multi-pion contributions to demonstrate that higher-order Fock components are crucial for accurately describing nucleon flavor asymmetry and to establish a unified framework for investigating similar nuclear effects in light nuclei like the deuteron.

Production of high-spin $\omega_J/\rho_J$ ( $J=2,3,4,5$ ) mesons in $\pi^{-}p$ reactions

Using an effective Lagrangian approach calibrated to existing data, this study successfully reproduces the production cross sections of high-spin $\omega_3$ and $\rho_3$ mesons in $\pi^- p$ reactions and predicts measurable, forward-peaked production rates for their $J=2,4,5$ partners, suggesting their feasibility for observation in future meson-beam experiments.

Observation of Robust and Coherent Non-Abelian Hadron Dynamics on Noisy Quantum Processors

This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.

Ab initio study of the halo structure in $^{11}$ Be

Using nuclear lattice effective field theory with high-fidelity chiral interactions, this study successfully reproduces the ground-state parity inversion and halo structure of $^{11}$ Be, revealing that the valence neutron occupies a $\sigma$ molecular orbital which enhances prolate deformation and creates a diffuse neutron tail distinct from the $\pi$ -orbital occupation in $^{10}$ Be.

The Gamow Golden Rule of Multichannel Resonances

This paper constructs the Gamow Golden Rule for multichannel scattering to derive decay distributions, partial decay constants, widths, and branching fractions for resonances with multiple decay modes, demonstrating the theory's application through two coupled-channel square well potentials.

Topological structure of the entanglement radius of Yang-Mills flux tubes

This paper expands on previous findings by investigating the topological structure of the entanglement radius $\xi_0$ in (2+1)D Yang-Mills theory, specifically examining how flux tube entanglement entropy behaves when the entangling region's cross-sectional length is comparable to the flux tube's intrinsic thickness.

Effective theory of surface oscillations in self-bound superfluid droplets

This paper develops a universal effective field theory for the low-energy surface oscillations of self-bound superfluid droplets, deriving the normal-mode eigenfrequencies, identifying a critical instability for the breathing mode, and quantizing the resulting ripplons to describe multi-ripplon states in systems like Bose mixtures.

Insensitivity of the Coulomb breakup of halo nuclei to spectroscopic factors

This paper demonstrates that Coulomb breakup cross sections for the one-neutron halo nucleus $^{11}$ Be are insensitive to spectroscopic factors when the asymptotic normalization coefficient is fixed, as confirmed by new calculations using a coupled-channel effective particle-rotor model that accounts for core excitation.

Systematic study of superheavy nuclei within a microscopic collective Hamiltonian: Impact of quantum shape fluctuations

This study employs a microscopic five-dimensional collective Hamiltonian based on relativistic Hartree-Bogoliubov calculations to reveal that quantum shape fluctuations significantly alter the predicted shell effects and shape transitions in superheavy nuclei, notably shifting magic numbers from $N=184, 258$ to $N=182, 256$ and eliminating bound $0^+$ states in transitional regions due to shallow potential wells.
