Using the data accumulated at LEP in 1989 and 1990 with the ALEPH detector, the inclusive and exclusive branching ratios of the r lepton have been measured assuming lepton universality in Z ~ decays. The inclusive branching fractions for the r decay into one, three, and five charged particles have been determined to be (85.45 _+ 0.97)%, (14.35 _+ 0.48)%,(More)
