Studies on two topics in the framework of broken supersymmetry are presented. Chapter I is a brief introduction in which the motivation and the background of this work are discussed. In Chapter II, the author studies the decay K/sup +/ ..-->.. ..pi../sup +/ ..gamma gamma.. in models with spontaneous supersymmetry breaking and find that it is generally suppressed relative to the decay K/sup +/ ..-->.. ..pi../sup +/ anti nu nu of the conventional model, except possibly for a class of models where the scalar quark masses are generated by radiative corrections from a much larger supersymmetry breaking scale. For a small range of scalar quark and photino mass parameters, the cascade decay process K/sup +/ ..-->.. ..pi../sup +/ ..pi../sup 0/ ..-->.. ..pi../sup +/ ..gamma gamma.. will become dominant over the anti nu nu mode. The author also comments on the possibility of probing the neutrino mass through the K/sup +/ ..-->.. ..pi../sup +/ ..pi../sup 0/ ..-->.. ..pi../sup +/ anti nu nu cascade decay. Chapter III is concerned with the implications of explicit lepton number violating soft operators in a general low energy effective theory with softly broken supersymmetry.
