Benchmark
- run 040430 (MDC1) -- 2k J/psi->mu+mu- K0s->pi+pi- events
Input
- two BtaCandidate lists from the event, "pionCandidates" and "muonCandidates"
- by default both parameters are set to "ChargedTracks", so no particle ID is used
Method
- use BtaV0Finder to make lists of K0s and psi candidates
- make histograms of K0s, psi and B0 combinations which are correctly found according to the "Default" BtaMcAssoc list
Output
- QaBetaMassPeaks_plot_RELEASE_040430.ps
- Mass resolutions from Paw fits shown on the above plots (the B0 mass is derived from the 4-vector sum of the four charged particles involved, so the resolution is poor by design)
