GMSB2 Trigger Study Explore trigger levels for two EF configurations: EF_3J60 L1 = 3J18 Study radial dependence L2 = 3J35 Study radial dependence EF_3J180 L1 = 3J70 Study radial dependence L2 = 3J120
GMSB2 Trigger Study Borrow code from Jovan to evaluate triggers. Overall efficiency Ratio of triggered events to total Radial Dependence Divide histograms of radius of 0 decay accumulated separately for triggered and un-triggered events NOTE: Two 0 decays per event!
GMSB2 Trigger Efficiencies L1_3J18 88.9% L2_3J35 85.5% EF_3J60 75.7% _______________________________________ L1_3J70 63.7% L2_3J120 60.0% EF_3J180 48.5%

RPV/LL DPD Data Steam Study What is the proposed RPV/LL Data Stream? It’s an OR of several triggers, ANDed with an OR of several offline requirements: Triggers: L1_MU40 OR L1_J120 OR L1_J70_XE30 OR stau, ORg55_tight OR2g17i_tight OR2g20 OR 3j60 Offline Cuts:One muon with pT > 40 GeV OR 3 jets with ET > 100 GeV OR One photon with ET > 20 GeV Question: Do these requirements bias the resulting sample in 0 momentum or decay length?
