  "description": "<p>The production of D\u204e\u00b1 , D\u00b1 and Ds\u00b1 charmed mesons has been measured with the ATLAS detector in pp collisions at s=7\u00a0TeV at the LHC, using data corresponding to an integrated luminosity of 280\u00a0nb\u22121 . The charmed mesons have been reconstructed in the range of transverse momentum 3.5&lt;pT(D)&lt;100\u00a0GeV and pseudorapidity |\u03b7(D)|&lt;2.1 . The differential cross sections as a function of transverse momentum and pseudorapidity were measured for D\u204e\u00b1 and D\u00b1 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\u00a0TeV were derived.</p>",
