Reconstruction of Ds mesons in the ALICE Experiment at LHC |
|
|
Content: |
Open Charm production is among the most direct probes of the early time
evolution of the quark gluon plasma produced in ultra-relativistic nuclear
reactions. The possibility of reconstructing the Ds mesons through their hadronic
decay channel ( Ds -> K + K - pi+ ) in the central barrel of ALICE detector is
studied. Ds mesons act as an useful probe to study hadronization mechanism in
heavy-ion collisions. The barrel tracking detectors provide the momentum information
and the particle identification of the charged particles. They also provide
an accurate measurement of the primary and secondary vertex positions and
of track impact parameters. The study of the selection cuts to optimize the combinatorial background rejection will be described. The Ds signal in the KKpi invariant mass distribution from p + p colisions at 7 TeV will be presented. |
