NON-DECOUPLING EFFECTS OF THE SM HIGGS-BOSON TO ONE-LOOP

We study the complete non-decoupling effects of the standard model Hig gs boson to one loop. Using effective field theory methods, we integra te out the Higgs boson and represent its non-decoupling effects by a s et of gauge-invariant effective operators of the electroweak chiral la grangian. In a previous work, we analyzed the non-decoupling effects i n the two- and three-point Green functions of gauge fields. We complet e here the calculation of the chiral effective operators by analyzing the four-point functions. We discuss in detail the relation between th e renormalization of both the standard model and the effective theory, which is crucial for a correct understanding and use of the electrowe ak chiral lagrangian. Some examples have been chosen to show the appli cability of this effective lagrangian approach in the calculation of l ow-energy observables in electroweak theory.
