Transverse Charge Distribution as a Probe of Nucleon Transversity
Wanchen Li, Xiaohui Liu, Ding Yu Shao
We introduce the transverse charge distribution as a spin-sensitive charge-flow probe for fragmentation and nucleon tomography. By measuring the angular distribution of net electri…

Sivers Tomography from Charge and Angle Only
Haotian Cao, Xiaohui Liu, Frank Petriello
We propose a one-point charge-correlator (OPCC) probe of the Sivers effect in back-to-back deep-inelastic scattering. This measurement uses only the signs and directions of charged…

Universality in the Near-Side Energy-Energy Correlator
Xiaohui Liu, Werner Vogelsang, Feng Yuan +1
We investigate the energy-energy correlator (EEC) of hadrons produced on the same side in annihilation or in leading jets in collisions. We observe a remarkable unive…
