Production of associated Υ and open charm hadrons in pp collisions at s√=7 and 8TeV via double parton scattering

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, Υ(1S)D0 , Υ(2S)D0 , Υ(1S)D+, Υ(2S)D+ and Υ(1S)D+ s , is reported....

Descrição
Resumo: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, 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. Published in JHEP 07 (2016) 052
