description	The production of D<sup>±</sup>, D<sup>±</sup> and D<sup>±</sup><sub>s</sub> charmed mesons has been measured with the ATLAS detector in pp collisions at √s = 7 TeV at the LHC, using data corresponding to an integrated luminosity of 280 nb<sup>-1</sup>. The charmed mesons have been reconstructed in the range of transverse momentum 3.5 < p<sub>T</sub>(D) < 100 GeV and pseudorapidity \|η(D)\|<2.1. The differential cross sections as a function of transverse momentum and pseudorapidity were measured for D<sup>±</sup> and D<sup>±</sup> production. The next-to-leading-order QCD predictions are consistent with the data in the visible kinematic region within the large theoretical uncertainties. Using the visible D cross sections and an extrapolation to the full kinematic phase space, the strangeness-suppression factor in charm fragmentation, the fraction of charged non-strange D mesons produced in a vector state, and the total cross section of charm production at √s = 7 TeV were derived.
