Abstract
Based on results of a search for the lepton-family-number-violating decay K+-->pi+µ+e- with data collected by experiment E865 at the Alternating Gradient Synchrotron of Brookhaven National Laboratory, we place an upper limit on the branching ratio at 2.1×10-11 (90% C.L.). Combining the results with earlier E865 data and those of a previous experiment, E777, an upper limit on the branching ratio of 1.3×10-11 (90% C.L.) is obtained.
