1) Update on Upsilon in p+p - Leszek Kosarzewski

Went through only the first 11 slides because Leszek has to leave BNL for airport at 11:00

• slide 9, suggest to select electron sample in data with higher purity (J/psi daughters or photonic electron), weight pt and y distribution to match that in embedding. Better also look other variables such as dca
• Slide 11, the combinatorial background is not described by the fit well. Also requested to calculate \chi^2 and ndf excluding the signal region.
