Shape Variables for the Doubly-Charmed B Decays

Abstract

We propose to use the hadronic shape variables to test the assumption of ``local duality'' in the doubly-charmed B decays, $B\to X_{c\bar{c}s}$. We compute these shape variables at leading order in parton model, and discuss how they can be compared with the experimental values.
