1 Optimization tau15i, tau20i, tau25i, tau35i on cuts menuJune07 Optimal cuts chosen looking at plots per ROI shown next. Plot left : weight is efficiency signal (ptVis>menu value,|eta|<2.5 *truth*) / efficiency background for a given cut (x,y bin is value of cut) Plot right : weight is efficiency signal (ptVis>menu value,|eta|<2.5 *truth*) for a given cut (x,y bin is value of cut) eff(Ji,W) = n passing cut x>xbin && y>ybin (for Et/ptLead) OR n passing cut x20 : 15918, pt>25 : 10746, pt>35 : 3857

2 tau15i EtCalib (GeV) PtLeadTrk (GeV) Input is all ROIs passing L1+L2 (menu June07 cuts), no cuts yet at EF. Only request to have a EF object in the ROI Bin steps of 2 GeV in both

3 tau20i EtCalib (GeV) PtLeadTrk (GeV)

4 tau25i EtCalib (GeV) PtLeadTrk (GeV)

5 tau35i EtCalib (GeV) PtLeadTrk (GeV)

6 tau15i IsoFrac EMradius After applying Et/ptLead track cut, look at these new distributions and choose cut on them Bin steps of 0.1 in both

7 tau20i IsoFrac EMradius

8 tau25i IsoFrac EMradius

9 tau35i IsoFrac EMradius

10 Proposed cuts keep efficiency total >= 60% after Et/ptTrk cut and >=50% after all cuts in EF (after all levels and wrt to pt>name of menu, |eta|<2.5) Tau15i tau25i EtCalib > EtCalib > PtTrackMax > 5000 PtTrackMax > 7000 Emradius < 0.12 Emradius < 0.1 IsoFrac < 0.31 IsoFrac < <= nTracks<= tau20i tau35i EtCalib > EtCalib > PtTrackMax > 5000 PtTrackMax > 7000 Emradius < 0.11 Emradius < 0.1 IsoFrac < 0.29 IsoFrac < <= nTracks<=8
