N2 - We study large top quark mass effects on low energy physics in the chiral-Lagrangian-formulated electroweak theories. We show that these radiative corrections can be easily obtained from a set of Feynman diagrams involving only the scalar Goldstone bosons and the fermions when the contributions of the order g (the weak coupling) are ignored. Using CERN LEP and SLAC Linear Collider data we constrain the nonstandard couplings, which might originate from the spontaneous symmetry-breaking sector, of the top quark to the electroweak gauge bosons.
