Abstract

We have searched for the decay of the [Formula presented] lepton into seven charged particles and zero or one [Formula presented]. The data used in the search were collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR) and correspond to an integrated luminosity of 4.61 [Formula presented]. No evidence for a signal is found. Assuming all the charged particles are pions, we set an upper limit on the branching fraction [Formula presented] at the 90% confidence level. This limit represents a significant improvement over the previous limit. © 1997 The American Physical Society.
