keyword=delta asymmetryHere the results of the analysis on the delta asymmetry.
The top left plot on the figure is the left arm delta asymmetry for the two runs where we took delta data. The top right is the right arm asymmetry time -1 (sign is oposite because it is transverse data). The middle plots are the charge asymmetries and the bottom plots are the livetime asymmetries.
There is a good agreement between both arm. The difference between Xiaochao's results and mine is still not solved.
Here the numbers (I took 38% target polarization, 83% beam polarization and 7% N2 dilution):
run 1455: -1.3% +/-0.6%(stat)
run 1456: -1.7% +/-0.6%
run 20455: +1.4% +/-0.6%
run 20456: +1.3% +/-0.6%
From the transverse data of GDH experiment, we expect about 1.31%. So there is a fair agreement.
