Jet transport coefficients computed in Hard-Thermal-Loop (HTL) effective theory are applicable at high temperature, while the medium created in heavy-ion collisions, at RHIC and LHC, predominantly samples the region near the QCD transition temperature. The dimensionless transport coefficient $\hat{q}/T^3$, calculated in leading order HTL theory, shows a monotonic rise with decreasing...
Target fragmentation provides a unique window into the correlation between the struck parton and the remnant system in semi-inclusive deep-inelastic scattering. While current and past studies of nucleon structure have largely focused on current fragmentation observables, the Electron-Ion Collider will enable precision measurements in the target-fragmentation region through its high luminosity,...
We combine the tools of global event shapes and jet electric charge into a unified factorization framework to probe quark flavor dynamics in the nucleon and the hadronization process. As a concrete example, we study jet charge measurements with the 1-Jettiness global event shape for Deep Inelastic Scattering (DIS) as a quark flavor probe of unpolarized or polarized parton distribution...
