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

The production of D ⁎± , D ± and D s ± 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 nb −1 . The charmed mesons have been reconstructed in the range of transverse momentum 3.5<p T (D...

description The production of D ⁎± , D ± and D s ± 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 nb −1 .
