## Abstract

Abstract Test of CP invariance in the reaction Z o → τ + τ − on the Z o peak is performed using the data sample recorded by the four Collaboration at LEP and SLD. From the non-observation of CP violation upper limits on the real ( ⋎Re(d τ W)⋎) and imaginary (⋎Im(d τ W)⋎) parts of the weak dipole moment of the τ lepton at 95% C.L. are derived. Results on measurements on weak magnetic moment is also reported.
