Book Description
Using the CLEO II detector at the e[sup+]e[sup -] storage ring CESR, we have determined the Michel parameters[rho], [zeta], and[delta] in[tau][sup[-+]][nu][bar[nu]] decay as well as the[tau] neutrino helicity parameter H[sub[nu][sub[tau]]] in[tau][sup[-+]][pi][sup 0][nu] decay. From a data sample of 3.02 x 10[sup 6][tau] pairs produced at[radical]s= 10.6 GeV, using events of the topology e[sup+]e[sup -][yields][tau][sup+][tau][sup -][yields] (l[sup[+-]][nu][bar[nu]])([pi][sup[-+]][pi][sup 0][nu]) and e[sup+]e[sup -][yields][tau][sup+][tau][sup -][yields] ([pi][sup[+-]][pi][sup 0][bar[nu]])([pi][sup[-+]][pi][sup 0][nu]), and the determined sign of h[sub[nu][sub[tau]]][1,2], the combined result of the three samples is:[rho]= 0.747[+-] 0.010[+-] 0.006, [zeta]= 1.007[+-] 0.040[+-] 0.015, [zeta][delta]= 0.745[+-]0.026[+-]0.009, and h[sub[nu][sub[tau]]]= -0.995[+-] 0.010[+-] 0.003. The results are in agreement with the Standard Model V-A interaction.
