Exclusive DDbar (Semileptonic)

  • Commissioning10 and Run2010A datasets, HLT_L1MuOpen OR HLT_L2Mu0 OR HLT_Mu3 triggers
    • /MinimumBias/Commissioning10-SD_Mu-Jun14thSkim_v1/RECO
    • /Mu/Run2010A-Jun14thReReco_v1/RECO
    • JSON Cert_132440-136119_7TeV_May27thReReco_Collisions10_JSON.txt
  • 1 track reconstructed as a globalMuon or trackerMuon, no other muon-ID selections applied
  • 3 other tracks besides the muon, no quality cuts
  • Net charge of the muon+3 tracks must be 0
  • No vertexing or kinematic cuts
  • No particle-ID (except for the muon), all combinations with both (K/pi) mass hypotheses for each track are plotted

  • Left: number of calo towers above 4 GeV
  • Center: m(Kpi) vs. m(Kmu)
    • Signal region (red) is based on the fitted mass from the inclusive D0->Kpi analysis +-3 sigma
  • Right: m(Kpi) projection

Exclusive DDbar (Hadronic)

  • Commissioning10 and Run2010A datasets, HLT_ZeroBiasPixel_SingleTrack OR HLT_ZeroBias trigger
  • 4 tracks with 0 net charge, no quality cuts
  • 0 extra calo towers above 4 GeV
  • No vertexing or kinematic cuts
  • No particle-ID, all combinations with both (K/pi) mass hypotheses for each track are plotted
