====== TTP97-34 The running of the b-quark mass from LEP data ====== 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. |**German Rodrigo, Arcadi Santamaria, Mikhail Bilenky** | |** Nucl.
