Description

A search for the lepton family number violating decay K+→π+μ+e- has been performed. We established an upper limit on its branching ratio of 1.1x10-9 at the 90% C.L. Measurements have also been made for the decay K+→π+e+e-. A description of the measurement technique and some preliminary results are presented. (orig.)
