About the quark currents in leptonic decaies of pseudoscalar mesons

With usage of obvious mechanisms of quark currents the amplitudes of leptonic decaies of pseudoscalar mesons are investigated. The estimation for a constant of leptonic decay of the D+ meson is obtained, f_D+ ~ 0.23 GeV.

Form factors of the Kmu3 decay in the spectator approximation of the Standard Model

We have calculated the parameter Ksi(0)=f-(0)/f+(0) of the Kmu3 decay in the spectator approximation of the Standard Model. It was obtained that Ksi(0) ~ -0.02.
