  1. L1 Rate Study: Update: GMT Emulator Change Nathaniel Amos

  2. GMT Emulator Changes • Rate spikes found from DTs around |η|=1.05 • Ivan Mikulec makes changes to GMT Emulator • Suppression of DT candidates with quality 3 in the bins above |η|>1.05. • Code contains cut at |η|=1.04 • Cuts on the center of the ηbin so effectively cut at |η|=1.05. • Updated GMT Emulator given to me today • Rerun my L1 Rate Analysis code • Compare old and new L1 η distributions

  3. L1SingleMu16_eta2p1 Before GMT edit After GMT edit η

  4. L1 Relative Rates Before GMT edit CSC-Only DT-Overlap Percent of L1 Rate DT-Only DT Overlap Region contributes 27% of L1SingleMu16_eta2p1 Rate RPC-Only CSC-Overlap DT Overlap Region contributes 12% of L1SingleMu16_eta2p1 Rate After GMT edit Percent of L1 Rate

  5. Conclusions • Ivan Mikulec changes GMT Emulator by cutting DT quality 3 tracks above |η|>1.05 • DT Overlap region spikes disappear • Overall L1SingleMu16 Rate drops by 19% • Expected maximum drop about ~20% from previous study • Next step: determine resultant efficiency changes
