Proton form factors in large NcQCD

The proton electromagnetic form factors are obtained using a particular model formula of QCDoo , QCD in the large Nc limit, which sums up the infinite number of zero-width resonances to produce an Euler's Beta function, Dual-QCDoo . The form factors F} (q2), F2(q2) and GM(q2) altogether consistently agree well with reanalyzed space-like data in the whole range of momentum transfer. Additionally, the ratio upGE/GM predictably is in good agreement with recent polarization transfer measurements at Jefferson Lab. The electric and magnetic radii are determined using this current world data.
