摘要：

We propose a method for determining gamma using B+/--->DK+/- decays followed by a multibody D decay, such as D-->K(S)pi(-)pi(+), D-->KSK-K+, and D-->K(S)pi(-)pi(+)pi(0). 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, gamma can be extracted without any hadronic uncertainty.
