摘要：
Two of the most powerful methods currently used to determine the angle. of the CKM Unitarity Triangle exploit B+ -> DK+, D -> K-S(0) pi(+) pi(-) decays and B-0 -> DK+pi(-), D -> K+K-, pi(+)pi(-) decays. It is possible to combine the strengths of both approaches in a "double Dalitz plot" analysis of B-0 -> DK+pi(-), D -> K-S(0) pi(+) pi(-) decays. The potential sensitivity of such an analysis is investigated in the light of recently published experimental information on the B-0 -> DK+pi(-) decay. The formalism is also expanded, compared to previous discussions in the literature, to allow B-0 -> DK+pi(-) with any subsequent D decay to be included.
