Book Description
This thesis presents a measurement of the tau Michel parameters. This measurement utilizes the highly polarized SLC electron beam to extract these quantities directly from the measured tau decay spectra using the 1993--95 SLD sample of 4,528 tau pair events. The results are[rho][sup e]= 0.71[+-] 0.14[+-] 0.05, [xi][sup e]= 1.16[+-] 0.52[+-] 0.06, and ([xi][delta])[sup e]= 0.85[+-] 0.43[+-] 0.08 for tau decays to electrons and[rho][sup[mu]]= 0.54[+-] 0.28[sup[minus]] 0.14, [eta][sup[mu]]=[minus]0.59[+-] 0.82[+-] 0.45, [xi][sup[mu]]= 0.75[+-] 0.50[+-] 0.14, and ([xi][delta])[sup[mu]]= 0.82[+-] 0.32[+-] 0.07 for tau decays to muons. Combining all leptonic tau decays gives[rho]= 0.72[+-] 0.09[+-] 0.03, [xi]= 1.05[+-] 0.35[+-] 0.04, and[Xi][delta]= 0.88[+-] 0.27[+-] 0.04. These results agree well with the current world average and the Standard Model.

Book Description
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.
