Abstract
The form factors of semileptonic , , , transitions are investigated in the framework of the light-cone sum rules with -meson distribution amplitudes, which play an important role in exclusive decays. The -meson distribution amplitudes, are a model-dependent form, so we consider four different parametrizations which can provide a reasonable description of from QCD corrections. The branching fractions of these transitions are calculated. For a better analysis, a comparison of our results with the prediction of other models is provided.
