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.

Book Description
This thesis is the beginning of a larger project to use BaBar to examine weak couplings through leptonic [tau] decay. I will use the ratio of Br... and Br... and the Michel parameters [rho] and [eta]. which describe the momenta spectrum of the daughter leptons. I studied using a simultaneous fit to the [tau] --> e and [tau] --> [mu] momentum spectra, using [rho], [eta], the ratio Br..., and total number of events as the fit variables. I created a simple Monte Carlo simulation which generated a. sample data spectrum and fit it for the Michel parameters [rho] and [eta]. I used the Monte Carlo to assess the impact of the uncertainties in the detector response function on the measurement of the ratio Br... My conclusion is that the three efficiency uncertainties equally have the greatest effect on the measurement of the number of events. The energy offset affects the measurement of Br... and that the energy scale and offset uncertainties have a non-negligible effect on [rho] and [eta].

Book Description
The II International Workshop on Tau Lepton Physics was held in Ohio, USA in September 1992. Its purpose is to gather the experts on tau lepton physics to examine the current understanding of the tau lepton physics and to assess future prospects. A particular emphasis of the Workshop was a detailed examination of the '1-prong problem': the discrepancy between the inclusive measurement of one-charged-particle decay branching ratio and the sum of the exclusive decays. The Workshop also stimulated new ideas on tests of the Standard Model using the third generation lepton and assessed the future prospects of the lepton physics.
