First observation of the decay B̄s0→D0K×0 and a measurement of the ratio of branching fractions B(B̄s0→D0K×0) B(B̄0→D0ρ0)

The first observation of the decay B̄s0→D0K×0 using pp data collected by the LHCb detector at a centre-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 36 pb-1, is reported. A signal of 34.4±6.8 events is obtained and the absence of signal is rejected with a statistical signific...
