Abstract

We report a measurement of the magnitude of the ντ helicity from τ-pair events taken with the CLEO detector at the CESR electron-positron storage ring. Events in which each τ undergoes the decay τhν, with h a charged pion or kaon, are analyzed for energy correlations between the daughter hadrons, yielding |ξh| = 1.03±0.06±0.04, with the first error statistical and the second systematic.
