Anomalous scaling of linear power corrections

Nonperturbative corrections to hadronic observables represent a critical obstacle to increasing accuracy at colliders. Long taken to scale simply as 1 / Q , where Q is the center-of-mass scattering energy, recent work has opened the path toward calculating the anomalous dimension that modifies that scaling. , the problem is complex, requiring a resummation involving arbitrary numbers of large-angle and low-energy gluons. Within a specific framework for kinematic recoil, we show that it reduces to a simple exponential for key observables like the thrust, C -parameter and energy correlators. This simplicity holds for a specific hadron-mass scheme, and also even beyond the two-jet limit.
