Abstract

We present analytic results for the three loop heavy top quark contributions of the electroweak ρ parameter. The calculation is carried out using the standard model lagrangian with vanishing gauge couplings. Within this gaugeless limit the masses of the Higgs boson M H and of the top quark m t are the single relevant mass scales. In the present calculation [1] we have investigated the behaviour of the ρ parameter in the limit of a Higgs mass equal to zero.
