Abstract
The production of J/Ψ mesons accompanied by open charm, ; of pairs of open charm hadrons are observed in pp collisions at a centre-of-mass energy of 7TeV using an integrated luminosity of 355 pb -1 collected with the LHCb detector. Model independent measurements of absolute cross-sections are given together with ratios to the measured J/Ψ ; open charm cross-sections. The properties of these events are studied ; compared to theoretical predictions. Copyright CERN.File in questo prodotto:
