Four and Three Loop Calculations in QCD: Theory and Applications

High Energy Physics - Phenomenology 2014-11-17 v1

Abstract

The talk briefly reviews the current state of the art in doing multiloop QCD calculations in a completely analytic way. In particular, we discuss recent analytical calculation of 4-loop O(alpha_s**3) gluino contribution to R(s) and its implications to the Z boson and tau-lepton decay rates.
