2 Gordon Watts (UW Seattle) Higgs Meeting 8/30/2002 Samples Data –Trigger list 8.0 Data –Trigger bit 9: CEM(1,5) At 10E30 this trigger bit was running 80 Hz At 30E30 about 240 Hz. –Reprocessed with p11 –Data extracted (not trig-simmed) MC –HW, W->e –Simulated and recoed with p11.08

3 Gordon Watts (UW Seattle) Higgs Meeting 8/30/2002 Summary At Level 1 –CEM(1,10) –CJT(2,5) –CJT(3,3) Not useful until calorimeter is fixed L1 MET –Would have been fantastic –Almost doubles rejection at L1, eff goes down 6%. At Level 2 –1 Jet above 20 GeV –2 Jets above 10 GeV –Was not able to get electrons to work The EMF in data was peaked strongly at one Still investigating this issue
