  • look at number of valid, bad,lost hits for STA muons, from DT, CSC, RPC separately, vs pT, eta.
  • verify the same info versus the trigger firing

Results

  • staLastHitDetId_v2.pdf:
    • many bad STA, on which we most certainly trigger
    • last hit position is on second CSC station--expected for punch-through.
    • -->
increase trigger rate with fake/bad muons;
 

Now what?

  • change the trigger, to fire when having 3 stations hits (as opposed to 2); L2 trigger.

GLB, STA, trig rates, firsts ... troubleshooting

Problem:

  • STA: 1/5events, GLB:1/.... --> many STA fakes (?) -->
dirrect implication on the trigger rates (xxx), higher than acceptable

Investigation

  • look at number of valid, bad,lost hits for STA muons, from DT, CSC, RPC separately, vs pT, eta.
  • verify the same info versus the trigger firing

Results

Now what?
