First observation of B+ -> D-s(+) K+ K- decays and a search for B+ -> D-s(+) phi decays

A search for B + → D s + K + K − decays is performed using pp collision data corresponding to an integrated luminosity of 4.8 fb −1 , collected at centre-of-mass energies of 7, 8 and 13 TeV with the LHCb experiment. A significant signal is observed for the first time and the branching fraction is de...
