Abstract

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 accumulated with the LHCb detector. The observation of five combinations, Y(1S)D , Y(2S)D , Y(1S)D , Y(2S)D and Y(1S)D , is reported. Production crosssections are measured for Y(1S)D 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.] −1 0 0 + + + 0 + s
