Event shapes are infrared-safe observables in QCD, which are relevant for studying jets and precision collider physics. There have been significant theoretical advancements in recent years regarding the analytic calculation of these observables. Many of these advancements are inspired by the representation of event shapes as integrated correlation functions of composite operators. In particular, this approach has allowed for the analytic calculation of event shapes at high orders of perturbation theory in maximally supersymmetric Yang-Mills theory and a detailed study of their collinear asymptotics in QCD. As a simple application of the correlation-function approach to event shapes, we consider charge-charge correlations in QCD at the leading perturbative order. The talk is based on work 2001.10806 with Emery Sokatchev, Johannes Henn, and Kai Yan.
