abstract

An analysis of the leptonic and semi-leptonic decays of heavy-light mesons
on the lattice is presented, in a non-perturbatively improved SW action
at two values of the lattice spacing in the quenched approximation to lattice
QCD. Results for the form factors of the decays D->K, D->pi and B->pi as well
as the decay constants fB and fD are presented. The soft-pion relation on the
lattice is considered. Finally preliminary results for the PS->V semileptonic
decays are presented.
