Measurement of the tau lifetime checks whether the tau couples to the charged weak current with the same universal coupling strength as the e and ..mu... The lifetime of bottom hadrons measures the weak coupling between the bottom quark and the charm and up quarks. Measurements of these lifetimes have been made with the MARK II detector at the e/sup +/e/sup -/ storage ring PEP at 29.0 GeV center-of-mass energy at the Stanford Linear Accelerator Center.
