Abstract

We study the

K_{L} - K_{S}

mass difference and the

K_{L} \to μ^{+} μ^{-}

decay rate in the Kobayashi-Maskawa model. If the matrix element

〈 {\bar{K}}^{0} | {[\bar{s} γ_{μ} (1 - γ_{5}) d]}^{2} | {\bar{K}}^{0} 〉

is sufficiently small (e.g., as estimated in the Massachusetts Institute of Technology bag model), then a stringent upper bound on the top-quark mass can be obtained.
