✦ Synopsis

This paper describes a measurement of the Michel parameters, r/, p, {, {~, the average u~ helicity, h.,, and the anomolous tensor coupling constant, ~w, in r lepton decays using the DELPHI detector. The T+T -pairs were produced at the LEP e+e -collider at CERN between 1992 and 1995. The Michel parameters, together with a measurement of the T polarisation, 79,, were extracted in a simultaneous fit to the two dimensional momentum spectra of leptonic and semi-leptonic T decays. The anomalous tensor coupling constant, ~w, was measured using the same selected data.
