History: AsymmetryCorrectionsPreview of version: 3To extract GEn/GMn, the true "physics" asymmetry must be determined. Since the "raw" asymmetry immediately measured from the data must be corrected for false asymmetry contributions, dilution, and finite acceptance effects.
I recommend that you work through the algebra to understand the correction factors for the asymmetry. Here, I will start with the number of events N in the positive (+) and negative (-) helicity state. Araw = (N+ - N-)/(N+ + N-)N+ = sigma+ L+ eta+ + Bckand likewise for N-.No formula specified.
