Abstract

A measurement has been made of the mean semi-muonic branching ratio for the decay of b-flavoured hadrons produced in e+e- annihilation events at PETRA. The result, (11.4±1.8±2.5)%, agrees well with other recent measurements and is consistent with the predictions of the spectator model with QCD and non-spectator corrections.
