[Clas12_first_exp] [EXTERNAL] RE:PAC48 slides

[Francois-Xavier Girod]

Concerning Kresimir's article raised by Franck
This is indeed one of the best arguments we have to argue for more data, as
I already said during the meeting several times

Kresimir's criticism is that we use ad-hoc functional forms to perform
global fits, and that these include poorly constrained extrapolations
Kresimir's approach, performing neural network fits, provide on of the
safest most conservative estimation of the D term uncertainties
Our strategy is diametrically opposite to his
To justify our strategy we need the fullest possible coverage in xB (the
variable that requires extrapolation)

Also note that combining RGA and RGK data we will be able to cleanly
separate the linear interference term from the DVCS^2 contribution

Best regards
