Abstract

Astronomy & Astrophysics Physical Sciences Physics Physics, Particles & Fields Science & Technology
We present an update of the search for the lepton family number violating decay tau-->mu gamma using 12.6 million tau(+)tau(-) pairs collected with the CLEO detector. No evidence of a signal has been found and the corresponding upper limit is B(tau--> mu gamma) <1.1x10(-6) at 90% C.L, significantly smaller than previous experimental limits.
