Reconstruction To Do List
- Generation
- Use genr8 for a2 production
- Use Pythia for background generation after removing a2 → η π0 from the MC data stream
- Use a2 charge exchange production xsection vs pythia total xsection to estimate number of signal and noise events
- Skim off (hd_filter) the wanted events by cutting on the total neutral energy (> 6 GeV) but record the total number of events before skimming
- Analysis
- After pruning the Pythia events, check the generated vs. reconstructed energy in a plot.
- Look at the a2 mass peak - adjust cuts on the eta and pi0 masses then look at the effect on the different angular distributions (i.e. Gottfried-Jackson angles, etc.)
- look at difference between reconstructed and generated z position for less than 65 cm
- look at single photon reconstruction efficiencies
- adjust the error matrix for the BCAL (look in PID/DPhoton_factory.cc)
- Gather all relevant DocDB documents and cross section publications at one spot on the Wiki.
Documents to Review
