Description
SCET provides a rigorous framework to perform resummation to obtain high-precision perturbative results for energy correlators, motivating a comprehensive study of the corresponding nonperturbative effects. Furthermore, testing the universality of nonperturbative parameters among different event shape observables is of theoretical interest. Information on nonperturbative power corrections of the energy-energy correlator (EEC) can be extracted from a renormalon analysis. We study the nonperturbative power corrections to the EEC using operator based methods in the framework of SCET, which allow us to relate the nonperturbative correction of the two-point correlator to higher-point correlators.
