Direct Measurement Of The Neutral Weak Dipole Moments Of The Tau Lepton

We present direct measurements of the neutral weak anomalous magnetic dipole moment, a{sub [tau]}{sup w}, and neutral weak electric dipole moment, d{sub [tau]}{sup w}, of the tau lepton. The dipole moments are measured by analyzing the decays of [tau] leptons produced in the annihilation of positrons and longitudinally polarized electrons on the Z boson resonance at the SLC. Using 6736 Z decays to {tau} {tau}− pairs elected from our 1993-1998 data sample we obtain Re(a{sub {tau}}{sup w}) = (0.26 ± 1.24) x 10−3, Im(a{sub {tau}}{sup w}) = ( -0.02 ± 0.66) x 10−3, Re(d{sub {tau}}{sup w}) = (0.18 ± 0.67) x 10 −17 e · cm, and Im(D{sub {tau}}{sup w}) = ( -0.26 ± 0.37) x 10−17 e · cm.
