I implemented a cut set similar to Cut Set 1, shown here .
The cuts are as follows:
- tight central lepton pT>20 GeV
- Raw Met>20 GeV
- Raw Ht>100 GeV
- at least 1 track/pi0 cluster with
- N(live)<7
- pT>10 GeV
The results of this cut set compared to the cut set 1 (the same except for the N(live) cut) are
| Source | Number in Cut Set 1 | Number in Cut Set 1 + N(live) Cut |
|---|---|---|
| Signal | 46.6 | 44.8 |
| W+jets | 208713 | 169236 |
| ttbar | 3018 | 2502 |
| Single Top (t-channel only) | 518 | 373 |
| Total Background | 212250 | 172112 |
We have reduced the signal by 3.8% and the background by 19%. Clearly, this cut is a keeper.
