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 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.
This study employs a hybrid approach alongside pure hadronic and string models to predict collective effects in upcoming O-O and Ne-Ne collisions at the LHC, aiming to determine the onset of quark-gluon plasma formation in small collision systems by comparing hydrodynamic and non-hydrodynamic evolutions.
This paper establishes new quasi-universal relations between static and dynamical tidal deformabilities of neutron stars that remain robust across diverse equations of state, thereby providing a simplified framework for incorporating dynamical tidal effects into gravitational-wave modeling while demonstrating that a one-mode approximation outperforms Taylor expansions in capturing the frequency-dependent response.
This study employs a Bayesian framework with multimessenger astrophysical data to demonstrate that while different parametrizations of density-dependent couplings in covariant density functionals yield broadly similar inferences, the specific functional forms significantly impact the equation of state and symmetry energy at suprasaturation densities, necessitating extended flexibility in the isovector channel up to the curvature coefficient for accurate modeling.
This paper demonstrates that the minimum domain-wall Skyrmions in low-energy QCD under strong magnetic fields are fermions with baryon number one, which can form by splitting previously identified bosonic domain-wall Skyrmions without energy cost.
This paper formulates out-of-equilibrium jet momentum broadening in QCD effective kinetic theory using a moment expansion to explicitly derive a leading-order correction to the spatial broadening tensor controlled by the medium's shear-stress tensor, thereby establishing a direct link between kinetic theory and event-by-event viscous hydrodynamic simulations for heavy-ion collisions.
This paper demonstrates that anomalous large-angle -scattering in $sd$-shell nuclei can be reasonably well reproduced within a single-folding model by utilizing microscopic nuclear densities from relativistic and non-relativistic mean-field theories combined with a unified, mass-dependent -nucleon interaction.
