Skim Standard Cuts
- Combined tracking confidence level (FOM) must be >= 5.73303 × 107 (+/- 5σ)
- Combined PID confidence level (FOM) must be >= 5.73303 × 107 (+/- 5σ)
- VERY loose cuts around invariant/missing mass peaks (keep enough data around peak to do sideband subtraction)
Proposed Exclusive Skims
- Note: "MM" is short for missing mass, "MMS" for missing mass squared, and "IM" for invariant mass
