  2. New MCP recommendation • Purpose • to recover some efficiency losses in 2012 data • to make the baseline and calorimeter muon selections more uniform • b-layer hits are not required anymore • no TRT selection is applied outside the region 0.1 < |η| < 1.9 • New: for 2012 data https://twiki.cern.ch/twiki/bin/viewauth/AtlasProtected/MCPAnalysisGuidelinesData2012 • Old: for 2012 data Moriondhttps://twiki.cern.ch/twiki/bin/viewauth/AtlasProtected/MCPAnalysisGuidelinesData2012Moriond

  3. status • Updated several cuts tau electron veto jet cleaning MET(jet calibration) • Etau channel • Electron corrections • 2nd lepton veto cuts • match our cut flow numbers on this part • Mutau channel • make clear the jet calibration issues which is related to MET • match our cut flow numbers on this part • Emu channel Will update all the results after compared with Keith and Laurel • Almost all of the systematic sources are considered in our analysis • Update all the central value/systematic study to our note Cross-check on jet-fake estimation and systematics calculation

  4. backup • if (fabs(Meta)<1.9&&fabs(Meta)>0.1) { • if(NHits >5 && (*mu_staco_nTRTOutliers)[i]/NHits <0.9) Pass_hits = true; • } else { • if(NHits >5 && (*mu_staco_nTRTOutliers)[i]/NHits <0.9 ) Pass_hits = true; • if(NHits <=5 ) Pass_hits = true; • } Pass_hits = true; • boolHits_CUT3 = ( !(*mu_staco_expectBLayerHit)[i] ) || ( (*mu_staco_nBLHits)[i] > 0 ) ; removed
