\Omb \rightarrow \Omc , \Omc ^* $ transitions: Model-independent bounds on invariant form factors

preprint1994arXivOpen access

Abstract

In this note we report some model-independent bounds involving transition form factors for $ \Omb \rightarrow \Omc $ and $ \Omb \rightarrow \Omc ^* $ and the nonperturbative matrix elements of the $ \Omb $ system. They are derived by using operator product expansion (OPE) in Heavy Quark Effective Theory .
