Abstract

We have searched for decays of the τ lepton into seven or more charged particles, using data collected with the OPAL detector from 1990 to 1995 in e +e − collisions at √8 ≈ M z . No candidate events were found and an upper limit on the branching ratio for τ decays into seven charged particles of 1.8 × 10 −5 at the 95% confidence level was determined. 6 References in this paper to specific charge states apply to the charge conjugate states as well.
