Le résumé fourni par la source

The p T -differential inclusive production cross section of the prompt charm-strange meson D + s in the rapidity range |y| < 0.5 was measured in proton-proton collisions at √ s = 7 TeV at the LHC using the ALICE detector.The analysis was performed on a data sample of 2.98 × 10 8 events collected with a minimum-bias trigger.The corresponding integrated luminosity is L int = 4.8 nb -1 .Reconstructing the decay D + s → φπ + , with φ → K -K + , and its charge conjugate, about 480 D ± s mesons were counted, after selection cuts, in the transverse momentum range 2 < p T < 12 GeV/c.The results are compared with predictions from models based on perturbative QCD.The ratios of the cross sections of four D meson species (namely D 0 , D + , D * + and D + s ) were determined both as a function of p T and integrated over p T after extrapolating to full p T range, together with the strangeness suppression factor in charm fragmentation.The obtained values are found to be compatible within uncertainties with those measured by other experiments in e + e -, ep and pp interactions at various centre-of-mass energies.
