Abstract
It is discussed in the Standard Model how a 1/N c expansion, where N c is the number of colors, may be a useful tool for resumming perturbative effects due to a heavy top quark. In particular, some recently proposed formulae for the two-loop resummation of the MW − MZ interdependence in terms of mt are re-obtained and, within the approximation of keeping only the leading term in 1/N c , it is shown how they are, as a matter of fact, valid to all orders in the top mass.Keywords
