[Clas12_deepana] Comparison Asymmetries CLAS12 - CLAS6

[Guillaume CHRISTIAENS]

Dear all,

As suggested by the deep processes working group, I've attempted a 
comparison of DVCS beam-spin asymmetry amplitude (after pion 
subtraction) with CLAS6 (I've used F-X analysis note to get CLAS6 points 
https://misportal.jlab.org/ul/Physics/Hall-B/clas/viewFile.cfm/2007-026.pdf?documentId=688).
First of all, since the binning and the kinematic distributions are very 
different, I don't have a good match between bins. I've compared the 
average value of xB/Q2/t for each bin and for each bin I've picked the 
CLAS6 bin with the closest average values. I've found only 6 bins out of 
my 16 that match a CLAS6 bin (sometimes it doesn't even match very well).

Attached is what I have in the end for the 6 bins.
I've labeled the bins from 1 to 6: bins 1 to 3 are "low |T|" bins while 
bins 4 to 6 are "high |T|" (1 have the same Q2/xB bins as 4, 2 same as 
5, 3 same as 6 ).
I have one bin with a big mismatch and 5 bins with a relatively good 
agreement, but, again, I don't think this is a good comparison because 
bins don't match well and there are sometimes very big bin-by-bin 
variations of the amplitude.

Best regards

Guillaume
