Description

Dynamics of high energy scattering in QCD are primarily probed through detector energy flow correlations. One important IRC safe energy-flow observable is the Energy-Energy Correlator (EEC). At leading power approximation in the back-to-back limit, EEC enjoys a factorization formula similar to the Drell-Yan production at small transverse momentum. Therefor studying the power corrections to EEC provides valuable insight to power corrections to Drell-Yan production. In this talk I will introduce a novel method to calculate power corrections to EEC by exploiting the power of conformal symmetry. I will show that there is a close correspondence between power corrections on one side, and twist and large spin perturbation in the operator product expansion of local correlator on the other side. I will demonstrate the method by computing the first NLP resummation for EEC.
