NON-DECOUPLING EFFECTS OF HEAVY-PARTICLES IN TRIPLE GAUGE BOSON VERTICES

Non-decoupling effects of heavy particles present in. beyond-the-stand ard models are studied for the triple gauge boson vertices gamma W+W- and Z(0)W(+)W(-). We show from a general argument that the non-decoupl ing effects are described by four independent parameters, in compariso n with the three parameters S, T and U in the oblique corrections. The se four parameters or the effective triple gauge boson vertices are co mputed in two beyond-the-standard models. We also study the relation o f the four parameters to the S, T, U parameters, relying on an operato r analysis.
