On the Edge of Safety: Charge-Charge Correlation in the Back-to-Back Limit
Pier Francesco Monni, Gherardo Vita, Zhen Xu +1
We investigate the Charge-Charge Correlation (QQC) in electron-positron annihilation as a probe of charge dynamics in Quantum Chromodynamics. While generally divergent beyond leadi…

Threshold Resummation for Semi-Inclusive Single-Hadron Production with Effective Field Theory
Zhen Xu, Hua Xing Zhu
Large double-logarithmic corrections are induced by soft gluon emissions near threshold in the semi-inclusive annihilation (SIA) distributions, and must be resummed to all…
