2010.07.09 Table of L0-BBC, L0-EEMC, and L2Egamma triggers biases

Updated on Mon, 2010-07-12 14:48. Originally created by seluzhen on 2010-07-09 18:19.

Real and simulated trigger decisions:

  • BBC stands for emulated L0 BBC trigger condition
  • EEMC stands for emulated Run 6 L0 EEMC (137832) trigger condition
  • L2 stands for emulated L2E-gamma (137641) trigger condition
  • Trig event satisfied to all three simulated trigger conditions: BBC+EEMC+L2
  • data-EEMC stands for real data L0 EEMC (137832) trigger condition
    (available only for fast offline data, not filled in yet)
  • data-L2 stands for real data L2E-gamma (137641) trigger condition

Data samples:

  • pp2006 data (3.4K events from st_physics production)
  • Pythia prompt photon simulations (147 events gamma-filtered for partonic pt=3-25GeV)
  • Pythia QCD 2->2 simulations (45 events gamma-filtered for partonic pt=6-9GeV)

Notations in the table:

  • XXX=0 - stands for XXX trigger did not fired
  • XXX=1 - stands for XXX trigger did fired
  • XXX=0 YYY=1 stands for XXX trigger did not fired, but YYY did fired
