Abstract

Exclusive semileptonic decays of

D

and

B

mesons to one and two pseudoscalar mesons are studied with respect to form-factor dependence, finite-width effects in intermediate resonant states, and non-resonant background terms calculated from chiral Lagrangians. Branching ratios, electron decay spectra, and asymmetry parameters for angular distributions are given for Cabibbo-Kobayashi-Maskawa-favored and -unfavored transitions, and compared to experimental data.
