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?

This paper proposes a theoretically clean and experimentally simple "one-point charge-correlator" probe for measuring the Sivers effect in back-to-back deep-inelastic scattering using only charged track signs and directions, which achieves factorization without relying on non-perturbative fragmentation functions and provides high-precision resummed predictions for future Electron-Ion Collider experiments.
This study investigates shape coexistence and mixing in the stable Zr, Mo, and Ru isobars by combining Covariant Density Functional Theory for ground-state deformations with a Bohr-Mottelson Hamiltonian featuring an octic potential for excited states, revealing that these phenomena significantly influence the nuclear structure near the Z=40 and N=50 shell closures.
This paper utilizes the MC-CGC event generator to demonstrate that LHCb data favors HERA-constrained initial conditions for the rcBK evolution equation and that the dense-dense factorization framework better describes mid-rapidity particle production than the dilute-dense DHJ approach, while also providing predictions for future ALICE FoCal measurements.
This review comprehensively examines the past decade's theoretical and experimental advances in laser-assisted nuclear decay and excitation, highlighting key developments in modeling laser-nucleus interactions and achieving breakthroughs in exciting specific isotopes like Th, Kr, and Sc to enable future applications in fundamental science and technology.
This paper presents a comprehensive study of inclusive charm and bottom quark pair production cross sections across a wide range of collision energies using next-to-next-to-leading-order (NNLO) calculations with the new MaunaKea code, demonstrating that these advanced predictions significantly enhance accuracy and reduce theoretical uncertainties compared to previous NLO results, thereby achieving agreement with experimental data and offering valuable constraints on gluon density and the bottom-quark mass.
This paper employs weakly coupled QCD kinetic theory to simulate minijet thermalization in a Quark-Gluon Plasma, demonstrating that including recoiling medium particles is essential for reconciling standard jet transport coefficients with kinetic evolution and establishing a phenomenological estimate for minijet quenching times.
Using the constituent quark model, this paper analyzes the radiative decays of various excited and charmed baryons in the flavor anti-triplet, providing branching ratios and decay widths that aid in identifying resonances and clarifying the nature of the and states.
Using a three-flavor PNJL model, this study demonstrates that the fourth-order correlation of baryon number and electric charge is more sensitive to magnetic fields at the chiral restoration phase transition than other fluctuations, making it a superior magnetometer for QCD.
This paper proposes a quantum circuit strategy for simulating lattice gauge theory by employing quantum group deformation to restore unitarity and reduce the resource scaling for two-qudit gates from to , demonstrating that q-deformation remains a reliable truncation method with significant advantages for quantum circuit synthesis.
This paper investigates the bound state of the + system by deriving a folding - potential from the HAL QCD - interaction, demonstrating that it fits a Woods-Saxon function and yields binding energies consistent with previous findings, while further validating the methodology through a comparative analysis of the - system.
