Top Radiative Corrections in Non-minimal Standard Models

Abstract

We derive the one-loop effective action induced by a heavy top in models with an extended Higgs sector. We use the effective action to analyze the top corrections to the $\rho$ parameter and to the Higgs-gauge boson couplings. We show that in models with $\rho \ne 1$ at tree-level, one does not lose generally the bound on $m_t$ from the $\rho$ parameter.
