Nondecoupling effects related to a large m(1) affecting nonoblique radiative corrections in vertices (Z (b) over bar b) and boxes (B-(B) over bar mixing and epsilon(K)) are sensitive to the mechanism of spontaneous symmetry breaking. In the framework of the effective chiral electroweak standard model there is only one O(p(4)) operator which modifies the longitudinal part of the W+ boon without touching the oblique corrections. This operator affects the Z (b) over bar b vertex, the B-(B) over bar mixing, and the CP-violating parameter epsilon(K) generating interesting correlations among the hard m(t)(4)lnm(t)(2) corrections to these observables.
