In Search of K sup + Yields pi sup + mu sup + e sup - and Other Rarities Seldom or Never Before Seen

摘要

The progress of AGS Experiment 777, a search for K sup + -> pi sup + mu sup + e sup - is described. Results on the decay K sup + -> pi sup + A sup 0 , where A sup 0 is a weakly interacting neutral particle that decays into e sup + e sup - and preliminary results on the direct decay K sup + -> pi sup + e sup + e sup - are presented as well as new limits on pi sup 0 -> mu sup + e sup - . 12 refs., 5 figs.
