摘要：
If the top is very heavy, m(t) much greater than M(z), the dominant radiative correction effects in all electroweak precision tests can be exactly characterized in terms of two quantities, the rho-parameter and the GIM-violating Z --> bbBAR coupling. These quantities can be computed using the standard model lagrangian with vanishing gauge couplings. This is done here up to two loops for arbitrary values of the Higgs mass.
