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.

4-momentum conservation as the principal framework for mesonic decay: The case of helium-5-lambda

This paper investigates the mesonic decays of the hypernucleus $^5_\Lambda$ He by applying 4-momentum conservation within relativistic kinematics to calculate monochromatic pion momenta for two-body decays and employing Monte Carlo simulations for three-body decays, revealing distinct momentum peaks and demonstrating that only a negligible fraction of events produce nucleons with momenta exceeding the Fermi limit of $^4$ He.

Production of high-orbital kaon excited states in the $K^{-}p$ reaction

This study employs an effective Lagrangian approach to successfully reproduce the production cross sections of high-orbital-excitation kaons in $K^{-}p$ reactions and predicts that other such states exhibit sizable, forward-peaked cross sections, indicating their strong potential for experimental observation.

Why fluctuations of conserved charges in the confining regime above $T_{ch}$ behave as if the quarks were free?

This paper resolves the apparent contradiction between free-quark-like fluctuations of conserved charges and confined mesonic correlators above the chiral crossover by demonstrating that while mesonic propagation remains string-bound, conserved quark number densities effectively bypass confinement through quark interchanges between overlapping color-singlet clusters, a phenomenon analogous to quark-hadron duality.

Physics-guided residual correction of $\alpha$ -decay half-lives based on the effective liquid drop model

This paper proposes a physics-guided framework that combines the effective liquid drop model with machine learning algorithms (specifically XGBoost and TabPFN) and physically motivated descriptors to significantly improve the prediction accuracy of $\alpha$ -decay half-lives in heavy and superheavy nuclei by correcting macroscopic baseline residuals.

Static linear response of hot and dense QCD matter to electromagnetic fields: Leading hard and soft QCD corrections

This paper computes the static electromagnetic susceptibilities of hot and dense quark-gluon plasma using perturbative QCD with leading hard and soft corrections, bridging the gap between perturbative calculations and Lattice QCD results to provide first-principle constraints on the plasma's electromagnetic response at finite baryon chemical potential where Lattice methods fail.

Diffractive structure functions from JIMWLK evolution

This paper computes diffractive structure functions using JIMWLK evolution constrained by HERA vector meson data, comparing results to existing measurements and providing predictions for nuclear modification factors and diffractive-to-total cross-section ratios at the future Electron-Ion Collider (EIC).

Hadronic tensor in lattice gauge theories by quantum computing

This paper demonstrates the direct computation of hadronic tensors in (1+1)-dimensional U(1) and SU(2) gauge theories using quantum algorithms on classical hardware, successfully extracting reliable hadron form factors that align with exact diagonalization results.

D-meson production via sequential hadronization in high-energy nuclear collisions

This paper investigates charm-quark hadronization in high-energy nuclear collisions using a sequential coalescence model coupled with Langevin transport, successfully reproducing ALICE's $D_s$ and $D^0$ elliptic flow data and predicting a low- $p_T$ peak in the $D_s/D^0$ yield ratio driven by strangeness enhancement.

Anomalies, Topology, and Hadron Structure in QCD

This review examines how quantum anomalies and vacuum topology in QCD resolve the $U(1)_A$ problem and generate hadron mass, while connecting these nonperturbative dynamics to modern studies of nucleon spin structure and partonic observables.

Teleportation in Proton Systems Revisited

This paper theoretically demonstrates that quantum teleportation of a spin state can occur in a three-proton scattering system involving an entangled proton pair, evidenced by the transfer of polarization from a target proton to a final-state proton when the target is polarized, or through residual spin correlations when the target is unpolarized.
