Abstract

We propose a method for determining \ensuremathγ using B^\ifmmode±\else\textpm\fi\ensuremath→DK^\ifmmode±\else\textpm\fi decays followed by a multibody D decay, such as \stackrel\ensuremath→DK_S\ensuremathπ^\ensuremath-\ensuremathπ⁺, \stackrel\ensuremath→DK_SK^\ensuremath-K⁺, and \stackrel\ensuremath→DK_S\ensuremathπ^\ensuremath-\ensuremathπ⁺\ensuremathπ⁰. The main advantages of the method are that it uses only Cabibbo allowed D decays, and that large strong phases are expected due to the presence of resonances. Since no knowledge about the resonance structure is needed, \ensuremathγ can be extracted without any hadronic uncertainty.
