Using the L3 detector, the branching ratio BR(b → ΠX) has been measured using a sample of of Z → bb̲ events tagged by high momentum and high transverse momentum leptons in one hemisphere and with missing energy in the opposite hemisphere. From a sample of 948 000 hadronic events we find BR(b → ΠX)= (2.4 ± 0.7(stat.) ± 0.8(syst.))%.
