Determining gamma using B->D^**K

High Energy Physics - Phenomenology 2009-11-10 v2

Abstract

We propose the use of B -->D^**K decay modes for a theoretically clean determination of the weak phase gamma. The self tagging decays of the neutral D^** mesons, makes a measurement of the b --> u\bar{c}s amplitude feasible. This overcomes the problem with the Gronau-London-Wyler proposal. Even an upper limit on the branching ratio for B^- -->bar{D}^{**0}K^- will place an assumption free, lower bound on gamma.
