I have switched to running over the upsilon 400 series for this analysis until the new embeded set is available.

Figure 1: MC pT distribution of all upsilons

Maybe they ran this in chunks of pT and I'm missing some.....

Figure 2: MC rapidity of all upsilons

Figure 3: Acceptance efficiency vs Emin where accepted is # events with eleEsum>Emin&&posEsum>Emin.  This is for mid rapidity |Uy|<1

I have picked 0.15 GeV as my minimum energy

Figure 4: Mid-rapidity Acceptance Efficiency vs rapidity for Emin = 0

Figure 5: Mid-rapidity Acceptance Efficiency vs rapidity for Emin = 0.15

This is my chosen minimum energy.  I'm still concerned about the asymmetry of the shape.  EDIT: asymetry is due to geometry.  Full BEMC barrel not available.

Figure 6: Mid-rapidity Acceptance Efficiency vs rapidity for Emin = 1 GeV

Figure 7: Efficiency calculations with binomial error bars.  Error bars are not correct when eff~100%

Figure 8: Efficiency vs rapidity for L2 trigger with trigger ID 117602

pT efficiency is flat as expected

Figure 9: L2 trigger efficiency vs rapidity for trigger 137602

I don't know why 117602 has the weird negative rapidity tail.  Figure 9 has no cuts on upsilon rapidity, but none were triggered on if |Uy| > 1

Figure 10: Eta vs Phi for MC upsilon daughter electrons with BEMC hits > 0

Figure 10 demonstrates the missing area for the BEMC that has caused the asymetry in the acceptance efficiency.  I will recalculate acceptance efficiencies for electron and positron phi>0, which will cause statistics to be limited but should me more accurate.

9357 upsilons with upsPhi > 0
1663 accepted

4734 upsilons at mid rapidity with upsPhi > 0
1628 accepted
 

Figure 11: Upsilon rapidity distribution for accepted upsilons with daughter particles having a phi > 0.  Acceptance is now symmetric as expected.

Figure 12: MC upsilon pT for all upsilons

This data set was the combination of two series, one with flat pT distribution from 0 to 10 and the other from 5 to 15.  So the number of upsilons/pT between 5 and 10 is twice the amount from 0-5 and 10-15.
