Observation of $B^0 \to \bar{D}^0 K^+ K^-$ and evidence of $B^0_s \to \bar{D}^0 K^+ K^-$

The first observation of the decay $B^{0} \to \overline{D}^{0}K^{+}K^{-}$ is reported from an analysis of $0.62 \ \mathrm{fb}^{-1}$ of $pp$ collision data collected with the LHCb detector. Its branching fraction is measured relative to that of the topologically similar decay $B^{0} \to \overline{D}^...
