• The production cross sections for prompt charmed mesons D 0 , D + , D ∗ + and D s + were measured at mid-rapidity in proton–proton collisions at a centre-of-mass energy s = 7 TeV with the ALICE detector at the Large Hadron Collider (LHC). D mesons were reconstructed from their decays D 0 → K - π + , D + → K - π + π + , D ∗ + → D 0 π + , D s + → ϕ π + → K - K + π + , and their charge conjugates.With respect to previous measurements in the same rapidity region, the coverage in transverse momentum ( p T ) is extended and the uncertainties are reduced by a factor of about two. The accuracy on the estimated total c c ¯ production cross section is likewise improved. The measured p T -differential cross sections are compared with the results of three perturbative QCD calculations.
