Introduction

• Study to investigate L1 and HLT (in)efficiencies and optimize selection for an express stream for very high energy diphoton events

• MC Samples:

• Produced at Caltech & Fermilab

• CMSSW_1_3_1_hlt2 with additional CVS tags:• V00-00-53 HLTrigger/btau

• V00-00-26 HLTrigger/xchannel

• V01-06-06 RecoLocalTracker/SiPixelClusterizer

• V01-00-06 L1Trigger/L1ExtraFromDigis

• V02-00-06 L1Trigger/L1ExtraFromMCTruthProd

• V00-00-67 HLTrigger/Configuration

• No Pileup

MC Samples

• Signal RS-1 G: • ~90k events each for 750, 1250, 1000, & 1500 GeV mass

samples (with c = 0.1)

• Background:• ~100k born and ~300k for box events

• CKIN(1) = 200 GeV • low limit of the invariant mass of the two outgoing photons,

with high end is set to infinity

• Done intentionally to reduce the amount of events to produce while keeping the most useful part of the backgrounds for our studies.

Selection

• Invariant mass, pt cuts

• Shape (S1/S9, S9/S25)

• ECAL Isolation

• HCAL energy deposition

• Track Isolation

• Jets

• Plots will be shown for only 750 GeV sample & born and box backgrounds

Next Steps

• Production:• CMSSW_1_3_1_hlt3

• Produce gamma+jet and QCD backgrounds with generator preselection (working on filter now)

• CompHep events for 2gamma+2jets and gamma+3jets (not the top priority now)

• Analysis:• Energy correction

• Optimize selection
