Abstract

Constraints on gluino and scalar quark masses from the K_L-K_S mass difference are analyzed and the consequences of CP violating phases in the super KM matrix are discussed. It is found that for a wide range of masses the contribution of super box diagrams to ε{lunate} dominates that of the ordinary box diagram. Depending on the scalar quark and gluino masses, ε{lunate}′/ε{lunate} may be smaller or larger than in the standard model and can be negative.
