Preliminary Analysis of runs in setC2
This analysis was preformed on the events in setC2. See here for details. I ran 48,000 qcd background events and 16000 W events using version 1.0 of my analysis program.
Fig 2: The number of primary tracks found for each event. The W events are on the left and the qcd background events are on the right.
The first cut an event is required to pass is that the transverse energy in a 3X3 patch of towers, centered on the tower with the highest energy, must be greater than 15GeV. All subsequent cuts are made only on events which pass this trigger.
Fig 3: The transverse energy deposited in the trigger patch for each event. The W events are on the left and the qcd background events are on the right.
For this analysis, I used the cuts I developed from looking at single particle events. For the 1-D histograms the W events are in black and the qcd background events are in red. For the 2-D histograms the W events are on the left and the qcd background events are on the right.
- cutOne: number of hit towers < 11
- cutTwo: number of hit U strips > 24 and < 42
- cutThree: not included
- cutFour: second pre-shower energy > 0.013
- cutFive: post-shower energy < 0.035
- cutSix: post-shower over full patch ratio < 0.0007
- cutSeven: three U strip over all U strip energy > 0.5 and < 0.8
- cutEight: seven U strip over all U strip energy > 0.65 and < 0.92
- cutNine: total U plane energy > 0.2
- cutTen: total U plane energy > 0.3
- cutEleven: post energy below line running through (0,0) and (0.3,0.05)
Fig 4. These plots show how many events passed a particular cut. W events are on the left and qcd background events are on the right. For reference, a total of 5997 W events passed the trigger and 6153 qcd background events passed the trigger.
