To-Do List

• long-term
  • gathering
  • large H_T search
  • investigating Z+1.7 TeV dijet mass
• tcmet
  • muon studes
    • finish up study of dpt/pt >1 muons (include nlayers, nhits, nlosthits)
      
    • use nlayers cut for bad muon rejection, include nlayers, dpt, dpt/pt in tcmet printout
    • slava's tcmet/pfmet study (put genmet in)
    • higher tail in zmm due to new RF: check if muon is also corrected as a pion by looking for tracks pt > 5 GeV dR < 0.1 to muon
    • exclusion cone for muons
      
  • study ( reco pt - gen pt ) vs. track kinematics
  • release validation
    • 382patch1
    • 390pre3
    • 382
    • 381patch3
    • 38
    • 3_8_5
    • 3_8_4_patch3 <<<----IMPORTANT
• susy
  • met templates
    • photon20 HLT cuts
    • rerun with more data
    • sync with ttdil (switch to jpts's)
    • fix template binning (0-30,30-60,60-90)
    • explore KEYS pdf's
    • implement b-tagging
    • use minbias to predict Z+0 jets met
    • understand Z+1 jet
    • include Wenu contamination: check distributions of haspixelseed, eta, jet neutral EM fraction, etc.
  • os susy search
    • check effect of: electron truth-matching, trigger selection, jpt corrections
    • check effect of including taus: reco vs. gen
    • ABCD: check 3rd variable Vienna group approach: section 17 of: http://cms.cern.ch/iCMS/jsp/db_notes/noteInfo.jsp?cmsnoteid=CMS%20AN-2010/208
    • understand ttbar spin correlations
    • where to get k-factor from? data or mc?
    • consider increasing met cut to 75 GeV for ee,mm final state
• tracking
  • TEC backplane studies
    • Check TEC- before Apr 28th vs. after Apr 28th
    • Cut on TEC tan(theta_trk) > X
    • Check TEC results with geometries from alignment group
• ntupling
  • ttbar alpgen samples
  • DYntupling: http://www.t2.ucsd.edu/tastwiki/bin/view/CMS/NtupleMakingInstructions

* for data-MC comparisons add an estimate on MET and JET scale using the prescribed 5% variation
for MET try/use deltaMET_H = +/-(vecMET + vecDilep)*0.05, which is a hadronic MET scale
* and, for completeness, similarly deltaMET_L = +/-(vecDilep)*0.01 .. can ignore it for now as it's small (I tried)
* for njets count jets with jetET*(1+/-0.05)
investigate how much rescaling is needed to get to an agreement.
