Abstract

In this paper, we present results of a feasibility study of a model-independent way to measure the angle φ₃ of the unitarity triangle. The method involves B^±→DK^± decays where the neutral D decays to the K⁰ _Sπ⁺π^- final state, together with the sample of decays of CP-tagged D mesons (produced, e.g. in ψ(3770)→DD̄ process) to the same final state. We consider different approaches to the extraction of φ₃ and obtain the expected statistical accuracy of the φ₃ measurement as a function of B and D_CP statistics.
