摘要：

We study the corrections to epsilon(')/epsilon in the minimal supersymmetric model at the leading order in QCD and QED. Supersymmetry can increase the standard model prediction for epsilon(')/epsilon by at most 40% for m(t) = 174 GeV, an enhancement which is indistinguishable from the present theoretical uncertainties. The most conspicuous effect of supersymmetry is a strong depletion of epsilon(')/epsilon. For certain choices of supersymmetric parameters, vanishing and even small negative values of epsilon(')/epsilon can be obtained for the top quark in the CDF range.
