L1 Trigger DPG

• Activity has ramped up in last 6 months
• Regular meetings started in August
• L. Agostino, J. Brooke, N. Leonardo, I. Mikulec
• Relatively limited effort for data analysis
• CRAFT
• Initiated centrally coordinated analysis effort
• Invited volunteers from wider trigger community
• Good response
• Further interest always welcome!
• All results show here are preliminary

• Comparison of L1 muon candidate with reco
• DT TF (Left) and RPC (Right)
• Take reco track ? at station 2, to match

Emulator vs data RCT
A. Savin M. Weinberg
Emul AND Data
Emul AND NOT Data
Data AND NOT Emul

• e/? candidates found by Regional Calorimeter
  Trigger hardware
• RCT configured to produce e/? from ECAL
• Compared with expectation
• Expectation ? run RCT emulator on trigger
  primitives readout by ECAL/HCAL
• Features
• White areas where ECAL was masked
• Red areas due to mistiming of ECAL TP readout

Run 69269

Emul AND Data
Emul AND NOT Data
Data AND NOT Emul

• As previous slide, but for RCT region sums
• (Region 4x4 trigger towers, input to jet-finder
  and energy sum algos)
• Many features, under investigation
• Overall picture is good

Run 69269

Emulator vs data RCT
J. Leonard K. Grogg

• E/? trigger turn-on curve
• Muon triggered sample
• RCT configured to produce e/? from HCAL towers
