Abstract (data abstract)
CERN-LHC. Measurement of the pT-differential inclusive production cross section of the prompt charm-strange meson D_s^+ in the rapidity range |y| < 0.5. The analysis was performed on a data sample of 2.98*10^8 events collected in 2010 in proton-proton collisions at sqrt(s) = 7 TeV at the LHC using the ALICE detector with a minimum-bias trigger, with a corresponding integrated luminosity of 4.8 nb^-1. The ratios of the cross sections of four D meson species (namely D^0, D^+, D*^+ and D_s^+) are determined both as a function of pT and integrated over pT after extrapolating to the full pT range, together with the strangeness suppression factor in charm fragmentation.
