Title: A Measurement of the Michel Parameters in Leptonic Decays of the Tau

Technical Report ·
DOI:https://doi.org/10.2172/813105· OSTI ID:813105

We have measured the spectral shape Michel parameters {rho} and {eta} using leptonic decays of the {tau}, recorded by the CLEO II detector. Assuming e-{mu} universality, we find {rho}{sub e{mu}}= 0.735 {+-} 0.013 {+-} 0.008 and {eta}{sub e{mu}} = 0.015 {+-} 0.061 {+-} 0.062, where the first error is statistical and the second systematic.
