Abstract
QCD sum rules are used to calculate the couplings of heavy-light quark pseudoscalar and vector mesons ( and ) with soft pions, both for finite and infinitely heavy quark mass. The couplings are also computed in the framework of a QCD relativistic potential model; in this approach the relativistic corrections due to the light quark are relevant.
