摘要：

The results of a lattice calculation of D-meson semi-leptonic decays into pseudoscalar and vector particles are presented. With respect to our previous studies of D --> K, K*, pi and rho-decays we have doubled the statistics and have studied the SU(3) breaking effects on the relevant form factors. In this letter we also predict the Zweig allowed contributions to the form factors and the corresponding partial rates for the semi-leptonic decays of D and D(s) into phi, omega, eta and eta' mesons.
