A universal probe of QCD spin physics from fragmentation energy correlator

We study the fragmentation energy correlator (FEC), which combines the nonperturbative fragmentation function with the infrared-safe energy correlator, as a new probe of the three-dimensional dynamics of QCD hadronization. We demonstrate, both theoretically and numerically, that FEC applies universally to inclusive had...

Hadronization effects and electroweak contributions in DIS one-jettiness

We study the structure of leading hadronization effects and the contributions of massive electroweak gauge boson exchange in the $\tau_1$ and $\tau_{1a}$ 1-Jettiness global event shapes for deep inelastic scattering (DIS). The leading hadronization effects in $\tau_1$ acquire a non-trivial dependence on the hard scatte...

Universality and Kinematic Dependence of Hadronization Effects in DIS Global Event Shapes

We propose a unified framework for a combined global analysis to constrain leading hadronization effects across the 1-Jettiness class of global event shapes for Deep Inelastic Scattering (DIS). We show that for the subclass of jet-based event shapes where the leading jet direction is determined dynamically event-by-eve...
