Rare semileptonic meson decays in R-parity violating MSSM

Abstract

We discuss rare meson decays $K^{+}\to {\pi }^{-}{\ell }^{+}{\ell }^{\prime +}$ and $D^{+}\to K^{-}{\ell }^{+}{\ell }^{\prime +}$ ($\ell ,{\ell }^{\prime }=e,\mu$) in a supersymmetric extension of the Standard Model with R-parity violation. Estimates of the branching ratios for these decays are presented.
