Skim Standard Cuts
- Combined tracking confidence level (FOM) must be >= 0.001
- Combined PID confidence level (FOM) must be >= 0.001
- VERY loose cuts around invariant/missing mass peaks (keep enough data around peak to do sideband subtraction if desired)
Proposed Skims
- Note: "MM" is short for missing mass, "MMS" for missing mass squared, and "IM" for invariant mass
| Channel | Topology | Mass Peak Cuts | % of Events Remaining |
|---|---|---|---|
| 2π | γp→π+π-p | -0.02 < MMS < 0.02 | |
| 3π | γp→π+π-π+(n) | 0.3 < MM < 1.6 | |
| ωππ | γp→ωπ+π-(p), ω→π+π-π0, π0→γγ | 0.1 < π0 IM < 0.17 0.5 < ω IM < 1.0 -0.02 < MMS < 0.02 |
