Measurement of D-mesons production at LHC with ATLAS
The D*±, D± and Ds± charm mesons were reconstructed in the range of transverse momentum pT(D(*)) > 3.5 GeV and pseudorapidity |η(D(*))| < 2.1 in data corresponded to an integrated luminosity of 1.4 nb−1. The fitted mass values were found to be in agreement with their world averages whi...

| Sumario: | The D*±, D± and Ds± charm mesons were reconstructed in the range of transverse momentum pT(D(*)) > 3.5 GeV and pseudorapidity |η(D(*))| < 2.1 in data corresponded to an integrated luminosity of 1.4 nb−1. The fitted mass values were found to be in agreement with their world averages while the observed invariant mass resolutions agree with Monte Carlo expectations. This study confirms the high performance of the ATLAS detector for precision tracking measurements. |
