Associated production of bottomonia and open charm hadrons in pp collisions at s=7 and 8 TeV is observed using data corresponding to an integrated luminosity of 3 fb −1 accumulated with the LHCb detector. The observation of five combinations, Y(1S)D 0, Y(2S)D 0, Y(1S)D +, Y(2S)D + and Y(1S)D s +, is reported. Production crosssections are measured for Y(1S)D 0 and Y(1S)D + pairs in the forward region. The measured cross-sections and the differential distributions indicate the dominance of double parton scattering as the main production mechanism.[Figure not available: see fulltext.]
