Abstract: (Springer)

Associated production of bottomonia and open charm hadrons in pp collisions at

\sqrt{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.
