Measurement of D *± meson production in jets from pp collisions at √s=7TeV with the ATLAS detector
This paper reports a measurement of D *± meson production in jets from proton-proton collisions at a center-of-mass energy of √s=7TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30pb - 1 for jets wit...

This paper reports a measurement of D *± meson production in jets from proton-proton collisions at a center-of-mass energy of √s=7TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30pb - 1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |η|<2.5. D * ± mesons found in jets are fully reconstructed in the decay chain: D *+ →D0π + , D0→K - π + , and its charge conjugate. The production rate is found to be N(D *± )/N(jet)=0.025±0. 001(stat.)±0.004(syst.) for D *± mesons that carry a fraction z of the jet momentum in the range 0.3<z<1.
