Comparison of D^(*) meson production cross sections with FONLL and GM-VFNS predictions

The differential cross sections for D*+- and D+- production, measured with the ATLAS detector in pp collisions at sqrt{s}=7TeV using an integrated luminosity of 1.1 nb^{-1}, have been compared with the FONLLL and GM-VFNS calculations. The NLO QCD predictions are consistent with the data in the visible kinematic range of transverse momentum pT(D^(*))>3.5GeV and pseudorapidity |eta(D^(*))|<2.1 within the large theoretical uncertainties.
