Heavy --> Light semileptonic decays of pseudoscalar mesons from lattice QCD

Abstract

We have computed the form factors for B --> pi and D --> K(pi) semileptonic decays on the lattice by using full non-perturbative O(a) improvement, in the quenched approximation. Our results are expressed in terms of few parameters which describe the q2-dependence and normalization of the form factors.
