Outline of analysis:

Final objective is both non-photonic electron cross-section and A_LL.

 

For both:

Event selection

 

Electron id: Identify inclusive electron sample

Photonic electron id: Identify photonic electron background

 Semi-inclusive electron: Inclusive electron - photonic electron

where in this case, 'photonic electron' is any inclusive electron that is successfully paired with a global track to create at least one opposite-charge pair that satisfies the photonic electron cuts.

 

Yield:

2005 electron yield

	all HT1	trig HT1	all HT2	trig HT2
Inclusive	7075	6402	7354	6257
Photonic	4146	3705	4686	3895
Semi-inclusive	2929	2697	2668	2362

 

2006 electron yield (not final cuts)
