摘要：

The p parameter is calculated to all orders in the top mass and leading order in an 1/N(c) expansion, where N(c) is the number of colors. The result agrees with the natural extrapolation from perturbation theory. Some consequences of our results are discussed. In particular, from the consistency requirement p > 0, a bound m(t) < 1.8 TeV is obtained.
