Abstract (data abstract)
CERN-LHC. The production cross sections of the prompt charmed mesons $\rm{D}^{0}$, $\rm{D}^{+}$, $\rm D^{*+}$ and $\rm D_{s}$ were measured at mid-rapidity in proton-proton collisions at a centre-of-mass energy $\sqrt{s_{\rm{NN}}}$=7 TeV with the ALICE detector at the Large Hadron Collider (LHC). D mesons were reconstructed from their decays $\rm{D^{0}}\rightarrow K\pi$, $\rm{D^{+}}\rightarrow K\pi\pi$, $\rm{D}^{*+}\rightarrow \rm{D}^{0}\pi\rightarrow K\pi\pi$, $\rm{D_{s}}\rightarrow\phi\pi\rightarrow K K \pi$ , and their charge conjugates. With respect to previous measurements in the same rapidity region, the coverage in transverse momentum pt is extended and the uncertainties are reduced by a factor of about two. The accuracy on the estimated total c-cbar production cross section is likewise improved. The measured $p_{\rm T}$-differential cross sections are compared with the results of three perturbative QCD calculations.
