First observation of B[bar]0 → J/ψK+K− and search for B[bar]0 → J/ψϕ decays
The first observation of the B̄0→J/ψK+K− decay is presented with a data sample corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions at a center-of-mass energy of 7 TeV collected with the LHCb detector. The branching fraction is measured to be B(B̄0→J/ψK+K−)=(2.53±0.31±0.19)×10−6, w...
