摘要：

In the framework of a QCD relativistic potential model we evaluate the form factors describing the exclusive decays B --> pi l nu and B --> Kl(+)l(-). The present calculation extends a previous analysis of B meson decays into light vector mesons. We find results in agreement with the data, when available, and with the theoretical constraints imposed by the Callan-Treiman relation and the infinite heavy quark mass limit.
