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.

Nucleon Parton Distribution Functions from Boosted Correlations in the Coulomb gauge

This paper presents the first exploratory lattice QCD calculation of nucleon unpolarized, helicity, and transversity parton distribution functions using a novel Coulomb gauge boosted-correlator method within Large-Momentum Effective Theory, demonstrating that the approach yields results consistent with global analyses and phenomenology while highlighting specific challenges with excited-state contamination in imaginary matrix elements.

Nuclear Fragmentation at Intermediate Energies in the DCM-QGSM-SMM Model

This paper evaluates the applicability of the newly developed DCM-QGSM-SMM model at lower energies (starting from 300 MeV/nucleon) by comparing its predictions with experimental data from FRAGM and FIRST/GSI and other existing models.

Solving BDNK diffusion using physics-informed neural networks

This paper reformulates the relativistic BDNK diffusion equation in flux-conservative form and solves it in $(1+1)$ D by comparing a second-order Kurganov-Tadmor finite volume scheme with a novel SA-PINN-ACTO framework, demonstrating that the neural network approach accurately reproduces converged solutions for smooth profiles while exhibiting expected limitations near discontinuities.

Impact of site-dependent noise configurations on Einstein Telescope science at low frequency

This study demonstrates that site-dependent Newtonian noise configurations, particularly below 10 Hz, critically influence the Einstein Telescope's scientific performance across key science cases, revealing that a 2L detector network with favorable low-frequency sensitivity can outperform triangular configurations and that poor low-frequency noise mitigation can negate the benefits of increased arm length.

The hidden sunrise in the energy-energy correlator

This paper presents a complete analytic computation of the energy-energy correlator (EEC) in $\mathcal{N}=4$ super Yang-Mills theory at next-to-next-to-leading order by resolving the elliptic sector through its identification with the sunrise integral's modular curve and expressing the result in terms of iterated Eisenstein integrals.

Quantum Localization Limit of Transport-Based Femtoscopy

This paper demonstrates that replacing classical point-emitter approximations with quantum-mechanical minimum-uncertainty Gaussian distributions in transport models significantly modifies proton-pair femtoscopic sources and correlations in small collision systems, thereby establishing the validity limits of the classical approach.

$\boldsymbol{\textit{Ab initio}}$ $n\alpha$ scattering using the Efros method

This paper presents the first *ab initio* application of the Efros method to $n\alpha$ scattering, demonstrating that utilizing harmonic oscillator expansions within the no-core shell model yields well-converged results in reasonable agreement with experiment, thereby establishing the approach as a practical tool for future nuclear reaction studies.

The effect of the coupling between the neutron multiplicity and the fission competition on the evaporation residue cross sections of the $^{48}$ Ca $+^{244}$ Pu reaction

This study demonstrates that a coupled treatment of neutron multiplicity and fission competition, as opposed to a conventional factorized approach, significantly improves the accuracy of survival probability predictions for the $^{48}$ Ca+ $^{244}$ Pu reaction, particularly for the 3n channel, while also highlighting the extreme sensitivity of evaporation residue cross sections to small variations in the fission barrier height.
