Semileptonic and nonleptonic two-body charmed meson decays in an effective model

Abstract

We analyze charm meson semileptonic $D \to V l \nu_l$ and $D\to P l \nu_l$ and nonleptonic $D \to P V$, $D \to PP$ and $D \to VV$ decays within a model which combines the heavy quark effective Lagrangian and chiral perturbation theory.
