Exploring CP violation with Bd0→DKS decays -: art. no. 116013

We (re)examine CP Violation in the decays B-d(0)-->DKS, where D represents D-0,<(D-0)over bar>, or one of their excited states. The quantity sin(2)(2 beta+gamma) can be extracted from the time-dependent rates for B-d(0)(t)-->(D) over bar**K-0(S) and B-d(0)(t)-->D**K-0(S), where the D**(0) decays to D-(*()+) pi(-). If one considers a non-CP-eigenstate hadronic final state to which both <(D-0)over bar> and D-0 can decay (e.g., K+ pi(-)), then one can obtain two of the angles of the unitarity triangle from measurements of the time-dependent rates for B-d(0)(t)-->(K+ pi(-))(D)K-S and B-d(0)(t)-->(K- pi(+))(D)K-S. There are no penguin contributions to these decays, so all measurements are theoretically clean.
