Update of the search for the neutrinoless decay tau ->mu gamma

Journal article

We present an update of the search for the lepton family number violating decay τ→μγ using 12.6 million τ+τ- pairs collected with the CLEO detector. No evidence of a signal has been found and the corresponding upper limit is script B sign(τ→μγ)<1.1×10-6 at 90% C.L., significantly smaller than previous experimental limits. ©2000 The American Physical Society.
