N2 - The pt-differential inclusive production cross sections of the prompt charmed mesons D0, D+, and D*+ in the rapidity range |y| < 0.5 were measured in proton-proton collisions at vs = 7 TeV at the LHC using the ALICE detector. Reconstructing the decays D0 → K-π+, D+ → K -π+π+, D*+ → D 0π+, and their charge conjugates, about 8,400 D 0, 2,900 D+, and 2,600 D*+ mesons with 1 < pt < 24 GeV/c were counted, after selection cuts, in a data sample of 3.14×108 events collected with a minimum-bias trigger (integrated luminosity Lint = 5 nb-1). The results are described within uncertainties by predictions based on perturbative QCD.
