A measurement of the Michel parameters, η, ρ, ξ, ξδ, and the average ντ helicity, hντ, in τ lepton decays is described together with the first measurement of the tensor coupling in the weak charged current. The results are consistent with the V - A structure of the weak charged current in decays of the τ lepton.

Michel Parameters

To test the Lorentz structure of the charged weak interaction, we study leptonic decays of tau lepton in the Belle experiment. We perform this test through the measurement of Michel parameters which appear in the differential decay widths of leptonic tau decays. In this paper, we discuss the preliminary results of the measurement of Michel parameters at Belle.
