Book excerpt: Branching-ratio limits obtained with the Crystal Box detector are presented for the rare muon decays ..mu.. ..-->.. eee, ..mu.. ..-->.. e..gamma.., and ..mu.. ..-->.. e..gamma gamma ... These decays, which violate the conservation of separate lepton-family numbers, are expected to occur in many extensions to the standard model. We found no candidates for the decay ..mu.. ..-->.. eee, yielding an upper limit for the branching ratio of B/sub ..mu..3e/ 3.1 x 10−11 (90% C.L.). A maximum-likelihood analysis of the ..mu.. ..--.. e..gamma.. candidates yields an upper limit of B/sub ..mu..e..gamma../ 4.9 x 10−11 and an analogous analysis of ..mu.. ..--.. e..gamma gamma.. candidates gives an upper limit of B/sub ..mu..e..gamma gamma../
