The running of the b-quark mass from LEP data

Abstract

Next-to-leading order QCD corrections to three jet heavy quark production in $e^{+}{e}^{-}$ collisions, including quark mass effects, are presented. The extraction of the b-quark mass form LEP data is considered and the first experimental evidence for the running of a quark mass is discussed.
