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 investigates heavy meson pair correlations in forward proton-nucleus collisions by incorporating unified Sudakov resummation within the Color Glass Condensate framework, demonstrating good agreement with LHCb data and predicting a robust mass hierarchy in nuclear suppression that highlights the sensitivity of heavy quarks to gluon saturation effects.
This paper presents an effective low-energy QCD framework treating atomic nuclei as bound systems of quarks, utilizing a modified bag model and gauge/gravity duality to accurately describe nuclear static properties, predict glueball decay channels, and explain the existence of a finite number of stable elements with a maximum atomic number of approximately 82.
This paper presents a causal and stable first-order relativistic BDNK magnetohydrodynamic framework in a boost-invariant background, revealing that magnetic fields respond strongly to temperature evolution while their feedback remains subleading, ultimately leading to a suppression of the low-mass dilepton spectrum due to enhanced cooling.
This paper presents a numerical solution for boost-invariant, cylindrically symmetric perfect spin hydrodynamics with wounded nucleon initial conditions, revealing a unique coupling between azimuthal and longitudinal spin polarization components that induces total polarization via the longitudinal magnetic and azimuthal electric fields.
This paper extends the Feshbach-Villars formulation of relativistic quantum mechanics to two-body systems of spin-0 particles, successfully separating the center-of-mass motion to derive a Feshbach-Villars-type equation governing the relative coordinate.
This paper presents a physics-informed neural network framework that successfully reconstructs the neutron-alpha scattering potential by embedding hard structural constraints and differentiable numerical solvers, thereby accurately recovering the resonance parameters and demonstrating the reliability of machine learning for nuclear inverse scattering problems.
This paper presents a one-dimensional femtoscopic analysis of correlations in Pb$-$Pb collisions at TeV using ALICE data, revealing source characteristics consistent with collective expansion and providing a high-energy baseline compatible with previous measurements and hydrokinetic model predictions.
The ALICE Collaboration reports the first measurement of isolated-prompt photon-hadron azimuthal correlations in Pb-Pb collisions at TeV down to a photon transverse momentum of 18 GeV/c, observing a strong suppression of associated hadron yields in central collisions that is compared with theoretical models and results from other experiments.
This paper presents a new evaluation procedure for independent and cumulative fission product yields in the spontaneous fission of Cf, utilizing a Bayesian Kalman filter to integrate experimental data with the Hauser-Feshbach Fission Fragment Decay model to produce mean values, full covariances, and consistent predictions for prompt and delayed neutron and -ray multiplicities.
Using a three-body potential cluster model with the hyperspherical Lagrange-mesh method, this study calculates the structural properties and asymptotic normalization coefficients of B and Li nuclei to derive a precise zero-energy astrophysical -factor of eV b for the Be()B reaction, revealing that the spin-2 channel dominates the capture process.
