					Starting a top analysis




     M. Cobal, University of Udine
     Bologna, 12 Feb 2007
    Which analysis to join
   Several topics uncovered or weakly covered for CSC
       Ttbar cross section
            Systematics
            Comparison of different techniques.(counting, mass fit etc..)
       Single top cross section
            Wt channel
   New subjects
       Top width
          hep-ph/9704243 (look at section V on page 10
          Eur Phys Jour C15 (2000, 2001), “The top Quark”, Revised April 2000
          by M. Mangano and T. Trippe
       Top charge (analysis done in fast simulation)
       ..
      Using AOD
   To learn using the AOD, please follow:
    https://twiki.cern.ch/twiki/bin/view/Atlas/TriesteAnalysisTutorial1

    The above page is linked from the Physics Analysis Tools
    (PAT) main page:
    https://twiki.cern.ch/twiki/bin/view/Atlas/PhysicsAnalysisTools

   Relevant top samples in AOD format are listed in:
    https://twiki.cern.ch/twiki/bin/view/Atlas/TopCSC

    (Ketevi Assamagan)
    Using Topview

  To know what is Topview:
https://twiki.cern.ch/twiki/bin/view/Atlas/TopView
 To have the detailed contents of the ntuples
   https://twiki.cern.ch/twiki/bin/view/Atlas/TopNtuple
 To know the preselection applied to objects

https://twiki.cern.ch/twiki/bin/view/Atlas/TopViewPreselection



(Akira Shibata)
     TopView ntuple availability
   Akira is producing ntuples for all samples whose AOD is
    available
   Availability is described in detail on the wiki:
    https://twiki.cern.ch/twiki/bin/view/Atlas/TopNtupleAvailability
   Many (not all, missing W+Jets and some of the newly created
    samples) AOD's are available in release 11 production but
    CSC 12 production is still at validation stage.
