Abstract We investigate the quark structure ofD andB mesons in the framework of a constituent quark model. To this end, we assume a scalar confining and a one gluon exchange (OGE) potential. The parameters of the model are adopted to reproduce the meson mass spectrum. From a fit to ARGUS and CLEO data onB→D * lv semileptonic decay we find for the Cabbibo Kobayashi Maskawa matrix elementV cb =(0.036±0.003) (1.32 ps/τ B )1/2. We compare our form factors to the pole dominance hypothesis and the heavy quark limit. For non-leptonic decays we utilize factorization and forB→D (*) X decays we finda 1=0.96±0.05, anda 2=0.31±0.03.
