Reweighted samples for aQGC model do not agree with generated
Dear experts,
I'm using the aQGC models lying here: http://
and after generating a sample of 30k events for a FT0 coupling value I tried reweighting it to a lower value of that coupling.
With the same run and param cards (except the coupling value and for 10k events) I generated a second sample corresponding to the smaller coupling value in order to compare the two but they do not seem to agree neither in terms of cross section nor in kinematics.
generated xs = 5.8884E-04 ± 1.17552E-06
reweighted xs = 5.9154E-04 ± 2.36962E-06
Do you have any idea what might be the problem?
Best regards,
Yannis
