FORM-FACTOR RELATIONS FOR HEAVY-TO-HEAVY AND HEAVY-TO-LIGHT MESON TRANSITIONS

Relations between the form factors that parametrize the hadronic matri x elements, in spectator decays of heavy mesons, have been derived by Stech within the constituent quark model. In this paper, we examine th ese relations using a slightly modified description of the meson state s. We find new and very general relations for some of the form factors . For the other form factors, we obtain small modifications to the rel ations previously derived by Stech, in the case of heavy-to-light tran sitions.
