$D\to \rho {\ell }^{+}{\ell }^{-}$ Decays in the QCD Factorization Approach

Thorsten Feldmann, Bastian Mueller, Dirk Seidel

We consider rare semileptonic decays of a heavy $D$-meson into a light vector meson in the framework of QCD factorization. In contrast to the corresponding $B$-meson decays, the na…
