Model-independent measurement of the CKM angle γγ using B0DK0B0DK0 decays with DK0Sπ+πDK0Sπ+π and K0SK+KK0SK+K / LHCb Collaboration
A binned Dalitz plot analysis of the decays B0DK0B0DK0, with DK0Sπ+πDK0Sπ+π and DK0SK+KDK0SK+K, is performed to measure the observables x±x± and y±y±, which are related to the CKM angle γγ and the hadronic parameters of the decays. The DD decay strong phase variation over the Dalitz plot is taken from measurements performed at the CLEO-c experiment, making the analysis independent of the DD decay model. [...]

The total branching fraction, its charmless component (Mpˉp<2.85 GeV/c2) and the branching fractions via the resonant cˉc states ηc(1S) and ψ(2S) relative to the decay via a J/ψ intermediate state are B(B+pˉpK+)totalB(B+J/ψK+pˉpK+)=4.91±0.19(stat)±0.14(syst),B(B+pˉpK+)Mpˉp<2.85GeV/c2B(B+J/ψK+pˉpK+)=2.02±0.10(stat)±0.08(syst),B(B+ηc(1S)K+pˉpK+)B(B+J/ψK+pˉpK+)=0.578±0.035(stat)±0.027(syst),B(B+ψ(2S)K+pˉpK+)B(B+J/ψK+pˉpK+)=0.080±0.012(stat)±0.009(syst).
