摘要：

The analysis of the presently available electroweak data including radiative corrections in the standard model suggests that the top quark weighs more than the Z0. We examine wether squark loops in the minimal supersymmetric model, particularly those involving stops (partners of the top quark), could reduce substantially the preferred range of top quark masses. Given the present lower bounds on squark masses, we find that stop effects can reduce the central value of mt by at most a few GeV, although they do make a very heavy top quark increasingly unlikely. © 1990.
