Description:
Author(s): Andrey Grozin, Johannes M. Henn, Gregory P. Korchemsky, and Peter Marquard We present the full analytic result for the three loop angle-dependent cusp anomalous dimension in QCD. With this result, infrared divergences of planar scattering processes with massive particles can be predicted to that order. Moreover, we define a closely related quantity in terms of an effective...
