Abstract
All experimental data on leptonic decays of Baryons available after the Kiev Conference on High Energy Physics (Sept. 1970) are used to fit the parameters of the Cabibbo theory. Especially new results on σ− and Λ leptonic decays and the values of the Σ± lifetime are included.
The data are consistent with the one angle Cabibbo theory. The results for the three parameters are:
$$\begin{gathered} \theta = 0.239 \pm 0.005 \hfill \\ g_1^F = 0.451 \pm 0.019 \hfill \\ g_1^D = 0.777 \pm 0.021. \hfill \\ \end{gathered} $$
