The running mass of the b quark as defined in the MS renormalization scheme, mb, was measured at the MZ scale using 2.8 million hadronic Z0 decays collected by the DELPHI experiment at LEP. The result is mb(MZ) = 2.67 ± 0.25(stat.) ± 0.34(frag.) ± 0.27(theo.)GeV/c2 which differs from that obtained at the γ scale, by mb(Mγ2)−mb(MZ) = 1.49±0.52 GeV/c2. This measurement, performed far from the bb production threshold, provides the first experimental observation of the running of the quark masses.
