We consider an effective non-linear Electroweak Chiral Lagrangian containing three would-be Goldstone bosons: w^a which transform non-linearly as a triplet under SU(2)_L X SU(2)_R and a Higgs singlet h plus its couplings to fermions via Yukawa interactions. This low energy model is valid for the range M_h,M_W,M_Z << s << 3 TeV.
Since the nex-to-leading order corrections due to fermion loops are proportional to the mass of the fermion we have performed the calculation for the heaviest fermion: top quark. We present both the finite and divergent part to the one-loop contribution, finding an agreement with other authors for the latter.
