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 ZL and WL form factors. We illustrate how such a form factor affecting the ZZLH coupling will be directly observable in e+e-→ ZH. We then show the spectacular consequences which would appear in the inclusive processes e+e-→ ZL+anything . Such a form factor could also affect the γW+LW-L and Z W+LW-L vertices and we show what effects this would generate in e+e-→ W+W- (especially in e+e-R→ W+LW-L) and in e+e-→ WL+anything . We finally mention the γγ→ W+W- process and several other processes in hadronic collisions which could be similarly affected.
