LVL1 rate/eff vs -threshold Dijet (weighted J1&J2 samples) Higgs 130 GeV, had-had and lep-had weighted by BR
LVL2 efficiency If LVL2 requirements are applied only to events passing LVL1: OLD NEW –dijet1: 1-4 evts/16k10.8%22% ± 10% –dijet2: 20-120 / 19k7.4%16% ± 2.3% –dijet3: 40-150 / 18k5.6%18% ± 1.9% –dijet4: 10-90 / 13k5.4%20% ± 2.9% –dijet5: 15-120 / 17k4.3%19% ± 2.3% –dijet6: 10-110 / 18k2.8%13% ± 1.8% –dijet7: 5-60 / 7k2.7%13% ± 2.6% –dijet8: 5-50 / 8k2.3%11% ± 2.1% –Lep-had:25.2%49% ± ~1% –Had-had:39.5%89% ± ~1% Our previous scheme was overestimating the dijet rejection (and underestimating sigal acept.) 20% ± 2.6%
Dijet Efficiency/Rate out of LVL2 Dijet 1-8 added according to cross-section. For Dijet1, used eff derived from csc dijet samples (thanks Erik!) - 180k events
Signal Efficiency Trigger about 25% of Higgs events
Conclusions Estimated signal/dijet efficiencies in a consistent manner: –Same code run over both samples –L2 applied to events passing L1 Will look at forward jets (thanks Anton!)

Update on H studies Catalin and Tony FTK meeting, July 13, 2006.
FTK update H→ Tony, Catalin By speeding up/adding rejection at LVL2, we can have a higher rate coming in from LVL1. Therefore some of the LVL1 threshold.
