SPIN 2006 Preliminary Result
Event Selection Criteria
- run belongs to golden run list, version c
- BBC timebin belongs to {7,8,9}
- spinDB QA requires: isValid(), isPolDirLong(), !isPolDirTrans(), !isMaskedUsingBX48(x48), offsetBX48minusBX7(x48, x7)==0
- ignore additional vertices
- trigger = MB || JP1 || JP2
- |eta| < 1.
- |global DCA| < 1.
- nFitPoints > 25
- flag > 0
- nSigmaPion is in the range [-1,2]
- Random Patterns
- First Look at Charged Pion Trigger Bias (needs to be updated with more deltaG scenarios, should take ~1 day)
- 2005 Charged Pion Data / Simulation Comparison
- Asymmetries for near-side and away-side pions
- Background from PID Contamination
- Data - Monte Carlo Comparison, Take 2
