ABSTRACT
In this paper, first, we achieve the first-order wave function of the heavy mesons through the Bethe-Salpeter equation with a confining kernel. Afterwards, by means of this function, the structure functions of the decays of B to D and D* are obtained, and the structure functions’ slope and curve are computed. The obtained results are suitably consistent with the empirical values. The flows expressing transitions according to the invariance structure functions, that solely depend on the momentum transfer (q2) between hadrons, are stated to describe the dynamics of the quarks inside the hadrons and weak hadronic decays. One of the methods for obtaining the structure functions is to apply the Bethe- Salpeter wave function (B-S). In this work, by virtue of the zero- and first-order B-S wave functions, the structure functions for the semileptonic transitions of heavy mesons (B→Dlv, B→D*lv ) are achieved.
