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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.78907.v1/t1","@type":"Dataset","description":"$p_{\\rm T}$-differential cross section of prompt $\\rm{D}^{0}$ mesons in pp collisions at $\\sqrt{s_{\\rm{NN}}}$=7 TeV in the rapidity interval $|y|$<0.5.
