Charm and bottom hadronic form factors with QCD sum rules

摘要

We present a brief review of some calculations of form factors and coupling constants in vertices with charm and bottom mesons in the framework of QCD sum rules. We first discuss the motivation for this work, describing possible applications of these form factors to charm and bottom decays processes.We first make a summarize of the QCD sum rules method.We give special attention to the uncertainties of the method introducing by the intrinsic variation of the parameters. Finally we conclude.
