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?

Using the basis light-front quantization formalism, this study reveals that relativistic effects induce novel "W"-shaped structures in the leading-twist distribution amplitudes of -wave axial vector quarkonia, highlighting the necessity of relativistic frameworks for accurately modeling heavy quarkonium production and structure.
This paper utilizes the operator product expansion within Pionless effective field theory to analyze high-momentum nucleon distributions in light nuclei, successfully extracting local-operator matrix elements from variational Monte Carlo data to accurately reconstruct single-nucleon distributions and establish approximate relations between single- and two-nucleon contributions in potentials lacking explicit non-nucleon degrees of freedom.
This paper applies transfer learning to fine-tune deep neural networks pretrained on carbon-12 data, successfully constructing robust, data-driven models for inclusive electron-nucleus cross sections across various nuclei that outperform existing phenomenological models while systematically analyzing the impact of fine-tuning depth, data availability, and kinematic coverage.
This study demonstrates that Kolmogorov-Arnold networks (KANs) significantly outperform traditional models in predicting nuclear binding energies with a low error of 0.26 MeV while simultaneously providing interpretable analytical expressions that align with classical nuclear physics theories.
This paper proposes a novel mechanism within the Energy Density Functional framework, attributing the origin and evolution of nuclear magic numbers to the interplay between the Dirac mass kinetic term (arising from spin-0 boson participation) and the spin-orbit term, thereby offering a unified explanation for shell structures in both stable and exotic nuclei.
This paper presents three predictions for partonic energy loss in ultrarelativistic light ion collisions by combining BDMPS-Z, weighted path, and JEWEL models with realistic O and Ne geometries to demonstrate how ion size characteristically influences energy loss in small quark-gluon plasma systems.
This paper introduces HPRMAT, a high-performance, GPU-accelerated R-matrix solver that utilizes mixed-precision arithmetic and optimized linear algebra to achieve significant speedups over legacy codes, thereby enabling large-scale coupled-channel nuclear physics calculations on standard consumer workstations.
This study utilizes AMPT and HIJING transport models to demonstrate that the splitting between proton and anti-proton dipolar flow () at mid-rapidity in Au+Au collisions increases at lower beam energies, serving as a sensitive probe of baryon transport and antibaryon annihilation in the hadronic medium.
This paper demonstrates that the plane-wave approximation used in a recent Trojan Horse Method analysis of the fusion reaction is fundamentally flawed due to the critical role of Coulomb distortions, rendering the extracted astrophysical factor unreliable and potentially misleading for low-energy fusion studies.
This paper systematically investigates baryon-baryon interactions in singly bottomed dibaryon systems using the chiral quark model, revealing that low-isospin and decuplet-decuplet channels favor stronger attraction and identifying numerous potential bound states that warrant further experimental verification.
