Аннотация:Associated production of bottomonia and open charm hadrons in pp
collisions at s√=7 and 8TeV is observed using data corresponding to an integrated luminosity of 3fb−1 accumulated with the LHCb detector. The observation of five combinations, Υ(1S)D0, Υ(2S)D0, Υ(1S)D+, Υ(2S)D+ and Υ(1S)D+s, is reported. Production cross-sections are measured for Υ(1S)D0 and Υ(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. This allows a precise measurement of the effective cross-section for double parton scattering.
