A METHOD TO DETERMINE THE TAU-NEUTRINO HELICITY USING POLARIZED TAUS

A method is presented to extract the tau neutrino helicity, or equival ently, the chirality parameter gamma(VA), independent of any tau polar ization which may be present. The method is thus well-suited to measur ements using taus produced from the Z(0) and is complementary to analy ses using tau correlations since it provides the sign of the chirality parameter which is otherwise unavailable without recourse to lower en ergy experiments where taus are unpolarized. Results of Monte Carlo st udies and comments regarding the use of the technique in experiments a re also included.
