Search for the muon-number--nonconserving decay. mu -->. e/sup +/ < or approx. =/sup +/e/sup -/

Journal Article · · Phys. Rev. Lett.; (United States)

A search has been performed for the muon-number--violating decay ..mu -->..e/sup +/e/sup +/e/sup -/. No candidate event has been found, the result yielding an upper limit for the branching ratio of B/sub mu3e/<1.3 x 10/sup -10/ (90% C.L.). From part of the data taken with a trigger that enhanced ..mu../sup +/..-->..e/sup +/e/sup +/e/sup -/..nu../sub e/nu-bar/sub ..mu../ events, eleven such events were observed. They agree in number and spectra with expectations based on standard electroweak theory.
