Top Radiative Corrections in Non-minimal Standard Models
Alex Pomarol
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 ρ parameter and to the Higgs-gauge boson couplings. We show that in models with ρ=1 at tree-level, one does not lose generally the bound on mt from the ρ parameter.
