  • Started studying B-meson decays to J/Psi for presenting at QM'08
  • Working Plans
    1. Generating B->J/Psi events with Pythia at 5.5TeV.
    2. Simulation, digitization, reconstruction are excuted(|Eta|<2.4, pT>3.5GeV).
    3. Getting GEN & RECO J/Psi Eta, pT, mass spectra and comparing.
    4. Using effective L1/L2 trigger combination option to get best J/Psi trigger efficiency.
    5. Mixing B->J/Psi event with heavy ion background(Hydjet).
    6. Secondary Vertex algorithm is used for distinguishing secondary J/Psi from prompt J/Psi.
