Universal Isgur-Wise form factors from QCD sum rules in HQET
/ Authors
/ Abstract
Abstract We review the role of the universal Isgur-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.
