Determination of the angle γ using multibody D decays in B ± → DK ±
نویسنده
چکیده
We describe a method for determining γ using B± → DK± decays followed by a multibody D decay. In the talk we focus on KS π−π+ final state, but other modes such as D → KS K−K+ and D → KS π−π+π0 can also be used. The main advantages of the method are that it uses only Cabibbo allowed D decays, and that large strong phases are expected due to the presence of resonances. Since no knowledge about the resonance structure is needed, γ can be extracted without any hadronic uncertainty.

Supersymmetric contributions to B → DK and the determination of angle γ
We analyze supersymmetric contributions to B → DK and B → D̄K processes. We investigate the possibility that supersymmetric CP violating phases can affect our determination for the angle γ in the unitary triangle of Cabibbo-Kobayashi-Maskaw mixing matrix. We calculate the gluino and chargino contributions to b → u(c̄s) and b → c(ūs) transitions in a model independent way by using the mass inserti...
متن کاملImproving Bounds on Γ in B ± → Dk ± and B ±,0 → Dx ±,0
In view of recent experimental progress in rate and CP asymmetry measurements in B → DK, we reconsider information on the weak phase γ which can be obtained from these processes. Model-independent inequalities are proven for sin γ in terms of two ratios of partial rates for B → DX s , where Xs is any multiparticle charmless state carrying strangeness ±1. Good prospects are shown to exist for us...
متن کاملRole of Charm Factory in Extracting CKM - Phase Information via B → DK
In this paper we study the impact of data that can be obtained from a Charm Factory on the determination of the CKM parameter γ from decays of the form B → DK where the D decays to specific inclusive and exclusive final states. In particular, for each exclusive final state f , the charm factory can determine the strong phase difference between D → f and D̄ → f by exploiting correlations in ψ(377...
متن کاملCP-tagged charm decays: relevance, status and prospects
The analysis of quantum-correlatedD − D̄ decays produced at the ψ(3770) resonance gives unique insight into quantities such as strong-phase differences and coherence factors. Knowledge of these parameters is invaluable for measurements of the CKM-angle γ (φ3) in B → DK decays. Results from CLEO-c analyses performed at the ψ(3770) resonance in a variety of decay channels are reported, and their c...
متن کاملConstraints on the unitarity triangle angle γ from Dalitz plot analysis of B0 → DKþπ− decays
The first study is presented of CP violation with an amplitude analysis of the Dalitz plot of B → DKþπ− decays, with D → Kþπ−, KþK−, and πþπ−. The analysis is based on a data sample corresponding to 3.0 fb−1 of pp collisions collected with the LHCb detector. No significant CP violation effect is seen, and constraints are placed on the angle γ of the unitarity triangle formed from elements of th...
