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⁻¹ accumulated with the LHCb detector. The observation of five combinations, Y(1S)D⁰, Y(2S)D⁰, Y(1S)D⁺, Y(2S)D⁺ and Y(1S)D_s ⁺, is reported. Production crosssections are measured for Y(1S)D⁰ 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.
