The use of quantum-correlated D0 decays for φ3 measurement

We report the results of the Monte Carlo study of the method to determine the CKM angle phi(3) using Dalitz plot analysis of D-0 produced in B-+/- -> DK +/- decay. Our main goal is to find the optimal strategy for a model-independent phi(3) extraction. We find that the analysis using decays of CP-tagged D mesons only cannot provide a completely model-independent measurement in the case of a limited data sample. The procedure involving binned analysis of B-+/- -> DK +/- and psi(3770) -> (K-S(0)pi(+) pi(-))(D)(K-S(0) pi(+) pi(-))(D) decays is proposed which, in contrast, allows not only to reach the phi(3) precision comparable to an unbinned model-dependent fit, but also provides an unbiased measurement with currently available data.
