Measurement of D *, D and D s meson production cross sections in pp collisions at s=7 TeV with the ATLAS detector

Popis výsledku v původním jazyce

The production of D⁎ , D and Ds charmed mesons has been measured with the ATLAS detector in pp collisions at s=7 TeV at the LHC, using data corresponding to an integrated luminosity of 280 nb1 . The charmed mesons have been reconstructed in the range of transverse momentum 3.5<pT(D)<100 GeV and pseudorapidity |η(D)|<2.1 . The differential cross sections as a function of transverse momentum and pseudorapidity were measured for D⁎ and D production. The next-to-leading-order QCD predictions are consistent with the data in the visible kinematic region within the large theoretical uncertainties. Using the visible D cross sections and an extrapolation to the full kinematic phase space, the strangeness-suppression factor in charm fragmentation, the fraction of charged non-strange D mesons produced in a vector state, and the total cross section of charm production at s=7 TeV were derived.
