Abstract
Combining the ratio of experimental kaon and pion decay widths, {gamma}(K{yields}{mu}{nu}{sub {mu}}({gamma}))/{gamma}({pi}{yields}{mu}{nu}{sub {mu}}({gamma})), with a recent lattice gauge theory calculation of f{sub K}/f{sub {pi}} provides a precise value for the Cabibbo-Kobayashi-Maskawa quark mixing matrix element vertical bar V{sub us} vertical bar =0.2219(25) or if three generation unitarity is assumed vertical bar V{sub us} vertical bar =0.222 1(24). Comparison with other determinations of that fundamental parameter, implications, and an outlook for future improvements are given.
