Description
We have measured the electric dipole moment (EDM) of the tau lepton using an 833 fb^-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. Using an optimal observable method, we obtain the EDM result with O(10^-17) ecm uncertainty. The result is consistent with no EDM at the present level of experimental sensitivity and improves the sensitivity by about a factor of three compared with the previous result.
