Measurement of charm production at central rapidity in proton-proton collisions at root s=2.76 TeV
Original language description
The p t-differential production cross sections of the prompt (B feed-down subtracted) charmed mesons D0, D+, and D*+ in the rapidity range |y|?<?0.5, and for transverse momentum 1?<?p t? <?12 GeV/c, were measured in proton-proton collisions at s=2.76TeVwith the ALICE detector at the Large Hadron Collider. The analysis exploited the hadronic decays D0??K?+, D+??K?+?+, D*+??D0?+, and their charge conjugates, and was performed on a Lint=1.1nb1 event sample collected in 2011 with a minimum-bias trigger. The total charm production cross section at s=2.76TeV and at 7 TeV was evaluated by extrapolating to the full phase space the p t-differential production cross sections at s=2.76TeV and our previous measurements at s=7TeV . The results were compared to existing measurements and to perturbative-QCD calculations. The fraction of cd D mesons produced in a vector state was also determined.
