Abstract

The constraints on the elements of the quark mixing matrix are updated and are used to study rare kaon decays. The top-quark-mass-dependent limit on the mixing matrix from the measurement of the branching ratio ${K}_{L}\ensuremath{\rightarrow}\ensuremath{\mu}\overline{\ensuremath{\mu}}$ is also included, and the effects on other rare decays are presented.
