Abstract: Nondecoupling effects related to a large mt affecting nonoblique radiative corrections in vertices (Zb̅ b) and boxes ( B- B̅ mixing and εK) are sensitive to the mechanism of spontaneous symmetry breaking. In the framework of the effective chiral electroweak standard model there is only one O(p4) operator which modifies the longitudinal part of the W+ boson without touching the oblique corrections. This operator affects the Zb̅ b vertex, the B- B̅ mixing, and the CP-violating parameter εK, generating interesting correlations among the hard mt4Inmt2 corrections to these observables.
