2009 pp Upsilon Sample

Code is at:

/star/u/rjreed/Upsilonpp2009/upsilonpp2006_v5
 

The below sample is from after the fix (10117028)

Used 2006 calibration

Out of 12852 candidates
Only 701 had 2 tracks which passed basic cuts (~5%)
track->flag() > 0 &&
track->flag() != 701 &&
track->flag() != 801 &&
track->flag() != 901 &&
track->pt() > 0.2 &&
track->nHitsFit() > 20 &&
track->nHitsFit() / (float)track->nHitsPoss() > 0.52 &&
0.0 * keV < track->dEdx() && track->dEdx() < 6.0 * keV);

None passed with addition offline cuts:

From 2006 trigger 137603
955106 candidates
71768 passed basic cuts (~7.5%)
273 passed offline (++,--,and +-) (~0.004%)

 

Looks Ok to me, not enough statistics to see a signal
