✦ Synopsis

We review the role of the universal Isgnr-Wise functions parameterizing the B meson semileptonic matrix elements to excited charm states in the infinite heavy quark mass limit. We also discuss the determination of such form factors by QCD sum rules in the framework of the Heavy Quark Effective Theory.
