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 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.
This paper theoretically extends the Lifshitz formula to demonstrate that the anomalous magnetic moment of Dirac fermions significantly enhances the fermionic Casimir energy under magnetic fields, particularly through the gapless behavior of the lowest Landau level, while providing quantitative estimates for electrons, muons, and constituent quarks.
Using Monte Carlo simulations on SU(3) gauge theory lattices, this study investigates topologically stable strings formed at domain wall junctions in the deconfined phase, revealing that their free energy is dominated by the walls and that thermal fluctuations near the transition point cause these structures to decay into confined-deconfined interfaces.
This paper calculates the electromagnetic dipole transition cross sections for reactions up to 20 MeV using high-order chiral effective field theory interactions and operators, validating results against existing experiments while providing new predictions via an adapted Efros method for future many-body applications.
This paper reformulates a presentation on baryonic bound states within the non-local Nambu–Jona-Lasinio model, demonstrating how a relativistic Faddeev approach reduces the three-quark problem to an effective quark–diquark Bethe–Salpeter equation to calculate baryon masses and form factors via coupled integral equations.
