Tag Composition and Mistag Studies

• Tag composition plots for Jet50 data
• Tag composition plots for Herwig dijet Pt40
• Data plots from ROOT Script.C
• MC plots from ROOT Script.C
• Test plots from ROOT Script.C
  • Pg1: Distributions for JetProb jets
  • Pg2: Number of good r-phi tracks for JetProb jets
  • Pg3: Signed impact parameter distribution for good r-phi tracks
  • Pg4: TrackProb (all, pos, neg) for good r-phi tracks
  • Pg5: JetProb for JetProb jets
  • Pg6: Missing Et for all, light and heavy jet events
  • Pg7: PrimeVtx Vx, Vy, Vz
  • Pg8: VxPrim Vx, Vy, Vz
  • Pg9: Number of pos and neg taggable jets in event
  • Pg10: Et, eta, NumGoodRPhi tracks for taggable jets
  • Pg11: Phi, eta and DeltaR Separation between jets in events with exactly2 taggable jets
  • Pg12: JetProb (pos and neg) for taggable jets in events with 2 taggable jets
  • Pg13: JetProb (pos and neg) for likely light jets in events with 2 taggable jets
  • Pg14: JetProb (pos and neg) for likely heavy jets in events with 2 taggable jets
  • Pgs 15,16,17: same as 10,11,12 but for TrackProb
  • Pg 18: Signed impact parameter distribution for all, light and heavy jets in di-taggable-jet events
  • Pg 19: Signed impact parameter significance distribution for all, light and heavy jets in di-taggable-jet events
• What is new:
  • Checked light flavor HEPG matching. Was including gluon->HF as light. Now doing a match of the jet to all final state hadrons to make sure b, c and light jets in the MC are assiged correctly.
  • Improved data selection: require 2 and only 2 JP jets, then require both jets to be taggable. For light jets, also require missingEt<15 GeV
  • Added missing Et histograms (probably useless for the purposes of this study but since I cut on it I wanted to see it)
  • Added d0Significance distributions
  • Saved ALL distributions in a root file
  • Analysis root script which reads in all distributions. We are ready for the next and most important steps...........
• Still to do:
  • Perhaps get templates from the different contributions and fit to extract fraction of HF in negative tags, fraction of secondary interactions in positive tags
  • Measure light, heavy, b, c tagging efficiencies in data and MC
