In this paper the two terms are important in the development of the theory of weak interactions; namely the problem of the theory divergensi VA, and the possibility of the existence of new role neutral currents. Both problems can be more satisfactory in the framework of gauge field theory, the new version. As an example of this new approach has been discussed the formulation of Weinberg and Salam model, especially for the lepton. The discussion is followed by a comparison between the forecast and the results of experiments teoritik. Description This ends with a summary and response-response model of the WAS and the general development in this field. M.O. Tjia, Departemen Fisika ITB,
