Observation of double charm production involving open charm in pp collisions at root s=7 TeV
The production of J/Ψ mesons accompanied by open charm, and 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 give...
