Leptonic decays of charmed mesons and the. nu. /sub tau/ mass

; ; ;
The possibilities of obtaining information on the tau-neutrino mass from study of the cascade decays of D/sup + -/ and F/sup +/ mesons via the channels tau/sup + -/+..nu../sub tau/(nu-bar/sub tau/) and tau/sup + -/..--> pi../sup + -/(rho/sup + -/) +nu-bar/sub tau/(..nu../sub tau/) are analyzed. It is shown that the most favorable conditions for observing these processes occur in e/sup +/e/sup -/ annihilation processes at energies corresponding to the D(F)-meson factory. It is possible in principle to lower the upper bound on the ..nu../sub tau/ mass by roughly an order of magnitude.
