  "abstract": "The measurement of the cross-section for charm production in pp collisions at the LHC is not only a fundamental reference to investigate medium properties in heavy-ion collisions, but also a key test of pQCD predictions in a new energy domain. The ALICE experiment has measured the D meson production in pp collisions at $\\sqrt{s}=7$ TeV. We present the analysis procedure for $\\rm D^{0}\\to \\rm K^{-}\\rm \\pi^{+}$ and for the calculation of efficiency and acceptance corrections. Finally, we show the preliminary results on $\\rm D^0$ cross section in pp collisions at $\\sqrt{s}=7$ TeV, measured in the region $2<p_{\\rm t}<12$ GeV/$c$ at central rapidity $|y|<0.5$. These results are compared to perturbative QCD predictions.",
