摘要：

We examine the implications for KL phenomenology of the recent experimental determinations of the form factor for the decay KL→e+e-γ. In particular, we reexamine the role of the top quark in light of the new measurements, and we show that for a branching ratio of KL→μ+μ- larger than 1.25 times the unitarty bound, as indicated by one experiment, the top quark mass has to be larger than 115 GeV. We predict a ratio between the rates for KL→e+e-γ and KL→μ+μ-γ of approximately 24. © 1990.
