$m_b$ at $M_Z$

The value of the $b$ quark mass at the $M_Z$ scale defined in the $\overline{MS}$ renormalization scheme, $m_b(M_Z)$, is determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be, \[ m_b(M_Z)=2.67 \pm 0.25\ ({\rm stat.}) \pm 0.34\ ({\rm frag.}) \pm 0.27\...

Sumario:The value of the $b$ quark mass at the $M_Z$ scale defined in the $\overline{MS}$ renormalization scheme, $m_b(M_Z)$, is determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be, \[ m_b(M_Z)=2.67 \pm 0.25\ ({\rm stat.}) \pm 0.34\ ({\rm frag.}) \pm 0.27\ ({\rm theo.}) \ {\rm GeV/c^2}. \] This analysis considers NLO corrections to the three-jet production rate including mass effects, and the result obtained agrees with the QCD prediction of having a running $b$-quark mass at an energy scale equal to $M_Z$. This is the first time that such a measurement has been performed far above the $b\overline{b}$ production
