Abstract:

We present results of a feasibility study of a model-independent way to measure the angle phi_3 of the unitarity triangle. The method involves B->DK decays where the neutral D decays to the K_S Pi+ Pi- final state, together with the sample of decays of CP-tagged D mesons (produced, e. g. in psi(3770)->DDbar process) to the same final state. We consider different approaches to the extraction of phi_3 and obtain the expected statistical accuracy of the phi_3 measurement as a function of B and D_CP statistics.

B: hadronic decay
D0: hadronic decay
CKM matrix: unitarity
Dalitz plot
numerical calculations: Monte Carlo
B+ --> D0 K+
B- --> D0 K-
D0 --> K0(S) pi+ pi-
psi(3770) --> D0 anti-D0
