Abstract

We assume that the Higgs doublet has a composite structure, respecting the main standard model properties, and therefore called Composite Standard Model (CSM), but leading (through Goldstone equivalence) to ZLZ_L and WLW_L form factors. We illustrate how such a form factor affecting the ZZLHZZ_LH coupling will be directly observable in e+eZHe^+e^-\to ZH. We then show the spectacular consequences which would appear in the inclusive processes e+eZL+anythinge^+e^-\to Z_L+anything . Such a form factor could also affect the γWL+WL\gamma W^+_LW^-_L and ZWL+WLZ W^+_LW^-_L vertices and we show what effects this would generate in e+eW+We^+e^-\to W^+W^- (especially in e+eRWL+WLe^+e^-_R\to W^+_LW^-_L) and in e+eWL+anythinge^+e^-\to W_L+anything . We finally mention the γγW+W\gamma\gamma\to W^+W^- process and several other processes in hadronic collisions which could be similarly affected.
