History: AsymmetryCorrectionsSource of version: 1To 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 ~~red:N~~ in the positive (+) and negative (-) helicity state. ~pp~A<sub>raw</sub> = (N<sub>+</sub> - N<sub>-</sub>)/(N<sub>+</sub> + N<sub>-</sub>) N<sub>+</sub> = �<sub>+</sub> L<sub>+</sub> �<sub>+</sub> + Bck ~/pp~ and likewise for -=N<sub>-</sub>. -=False Asymmetries=- History |
