  We study the complete non-decoupling effects of the standard model Higgs
boson to one loop. Using effective field theory methods, we integrate out the
Higgs boson and represent its non-decoupling effects by a set of gauge
invariant effective operators of the electroweak chiral Lagrangian. In a
previous work, we analyzed the non-decoupling effects in the two and three
point Green's functions of gauge fields. We complete here the calculation of
the chiral effective operators by analyzing the four point functions. We
discuss in detail the relation between the renormalization of both the standard
model and the effective theory, which is crutial for a correct understanding
and use of the electroweak chiral Lagrangian. Some examples have been chosen to
show the applicability of this effective Lagrangian approach in the calculation
of low energy observables in electroweak theory.
