dc.descriptionUsing limits of large energy effective theory and heavy quark effective theory we propose a simple parametrization of the heavy to light H to V semileptonic form factors. Then we reconsider D to V l nu_l decays within a model which combines heavy meson and chiral symmetry. In our Lagrangians we include contributions coming from excited charm meson states, some of them recently observed. Within this framework we determine all parameters describing the shapes of the form factors and calculate branching ratios and helicity ratios for all D to V l nu_l decays.
