AbstractAbstract
[en] The constraints on the γW+W- and Z0W+W- couplings are summarized. They essentially follow from various symmetry requirements which are weaker than the ones embodied in the SU(2)L*U(1)Y theory. The theoretical considerations lead to a well-defined systematic procedure for the analysis of future data. The helicity amplitudes for e+e-→W+W- are discussed and, in particular, the high-energy limit of s>>4MW2, relevant at an energy of 500 GeV, is analyzed. (K.A.) 18 refs., 4 figs., 4 tabs
