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 presents a precise determination of the strong coupling constant through a global fit of heavy jet mass data, utilizing state-of-the-art theoretical predictions that combine fixed-order calculations, multiple resummation orders, and first-principles power corrections to demonstrate the critical role of resummation in achieving robust results and revealing evidence for negative power corrections in the trijet region.
This paper computes the exact kinematic contribution to diffractive deep inelastic scattering structure functions, demonstrating that previous high-energy approximations are insufficient and revealing an equally important soft quark contribution alongside the soft gluon term at high .
Using QCD sum rules with dimension-12 condensates, this study calculates the mass spectra of hexaquark states and finds that the ground states lie around 5.8 GeV, consistent with BESIII's non-observation of a near-threshold bound state, while also predicting masses for hidden-bottom candidates.
This contribution proposes and demonstrates that the utilization of cascade decay pathways via nuclear excitation by inelastic electron scattering (NEIES) and nuclear excitation by electron capture (NEEC) in storage rings and electron beam ion traps can significantly increase the production yield of the Th isomer, thereby facilitating its application in nuclear clocks and precision metrology.
This paper demonstrates that magnetic field-induced mixing between charged pions and longitudinally polarized rho mesons, amplified by rho wave-function renormalization suppression, provides a robust mechanism explaining the non-monotonic behavior of charged pion masses observed in lattice QCD.
This paper utilizes a Dyson-Schwinger and Bethe-Salpeter approach to demonstrate that the transition from chiral symmetry breaking to restoration in light meson spectra is governed by the location of quark propagator poles relative to the integration domain, offering new insights into the potential emergence of chiral spin symmetry in QCD.
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.
