Digi rate update

Digi rate update. Added Matched LCT’s from ME1/1A chambers in MC Had to switch from using LCTs from raw data unpacking to ones created with trigger emulator using wire and comparator digis Two samples nearly identical, looking at few discrepancies to determine small changes

Presentation Transcript

  1. Digi rate update • Added Matched LCT’s from ME1/1A chambers in MC • Had to switch from using LCTs from raw data unpacking to ones created with trigger emulator using wire and comparator digis • Two samples nearly identical, looking at few discrepancies to determine small changes • Larger differences when comparing two approaches with real data • Scanned through 25 events with activity in ME4/2 • 24 had no other activity in rest of muon system • 23 had late ALCT • How to distinguish these as cosmics vs neutron background?

  2. ALCT Rates Cousins paper result -14 TeV With neutron background (solid) and without (dashed)  900 GeV  • New results have much larger fluctuations between chambers • Discrepancy between data and MC larger in 2360 GeV sample • Rate using x-section of 55.2 mb and L=10^34 from Cousins paper  2360 GeV

  3. CLCT rates Cousins paper result -14 TeV With neutron background (solid) and without (dashed)  • Similar features to ALCT rates 900 GeV   2360 GeV

  4. Matched LCT rates Cousins paper result -14 TeV With neutron background (solid) and without (dashed)  900 GeV   2360 GeV

  5. Whats next • Single layer background rate with zero luminosity • Single layer rate at increaing luminosities • Update with increasing luminosities and energies
