  • No worries about cutting off B mesons travelling out of the detector range in wrong direction!?Bplus_DIRA.gif

  • dll mu-e why is there a strange peak around 0 when the likelihood for electron and muon is the same? muminus_PIDe.gif
  • Counter output of run over Run1 Events 1-30000 with v loose preselection cuts (mass window on B 4GeV and chi2/ndof vertex fit of B < 100 !). Interesting asymmetry in reconstruction of B+ and B-
    "# B+ -> pi+ mu+ mu- " 29192 279088 9.5604 21.417 0.0000 1026.0
    "# B- -> pi- mu- mu+ " 29192 274857 9.4155 20.984 0.0000 917.00

  • To loop over the root file produced by DaVinci use the following commands (should really run on TChain but my tchain only contains the one file) TFile * filesignal = TFile::Open("rfio:///castor/cern.ch/user/j/johndan/DaVinciAnalysis/Bu_pimumu_Lumi2_Run_1.root"); filesignal.cd("DecayTreeBu2PiMuMu") TTree * tree = gDirectory->Get("Bu2PiMuMuTuple") tree.MakeClass("Optimisation")
