Measurement of the running b-quark mass using $e^{+}{e}^{-}\to b\bar{b}g$ events

A. Brandenburg, P. N. Burrows, D. Muller +2

We have studied the determination of the running b-quark mass, $m_b(M_Z)$, using $Z^0$ decays into 3 or more hadronic jets. We calculated the ratio of $\ge 3$-jet fractions in $e^+…
