Exploring CP Violation with B 0 d → DK S Decays

We (re)examine CP violation in the decays B d → DKS, where D represents D, D0, or one of their excited states. The quantity sin(2β + γ) can be extracted from the time-dependent rates for B d(t) → D̄KS and B d(t) → DKS, where the D decays to Dπ. If one considers a non-CP-eigenstate hadronic final state to which both D0 and D can decay (e.g. Kπ), then one can obtain two of the angles of the unitar...

Studies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays

We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...

Observation in BaBar of a Narrow Resonance in the D s π 0 System at 2317

The BABAR collaboration has observed a state of mass 2317 MeV/c 2 which decays to D s π 0 , using 91 fb −1 of data from asymmetric e + e − collisions of energy around 10.6 GeV produced by the PEP-II storage ring. The observed width is compatible with the experimental resolution, indicating that the state is narrow, with Γ < 10 MeV. Properties of the state are presented, and implications are dis...

Lhcb Strategies for Γ from B → Dk

One of the most promising ways to determine the angle γ of the CKM unitarity triangle is through measurement of the tree level processes B → DK. The LHCb collaboration has studied the potential of these decays employing the Atwood-Dunietz-Soni (ADS) and Dalitz methods, making use of a large sample of simulated data. For each method the expected sensitivities to the angle γ are presented in this...
