| Abstract: | In this article, results of the analysis of 225 000 τ+ decays in flight recorded at the CERN-PS with an electronic detector are presented. A quadratic fit of the matrix element |M|2 ∝ 1 + aY + bX2 + cY2 gives the following values for the parameters: a = 02814 ± 0.0082; b = ?0.099 ± 0.019; c = ?0.001 ± 0.023. |
