“…In [25] different PDFs sets were examined and the momentum transfer dependence of the GPDs H(x, t, ξ = 0) and E(x, t, ξ = 0) was obtained which give the best descriptions of the electromagnetic form factors of the proton and neutron simultaneously. It allows us to calculate two different form factors: the electromagnetic form factors can be represented as the first moments of GPDs H(x, t) and E(x, t), and the integration of the second moment of GPDs over x gives the momentumtransfer representation of the form factor A(t), which is reflects the matter distribution in the hadron (see [8,9,25]).…”
