Query: Interpretation of the Flavor Dependence of Nucleon Form Factors in a
  Generalized Parton Distribution Model   We give an interpretation of the $u$ and $d$ quarks contributions to the
nucleon electromagnetic form factors for values of the four-momentum transfer
in the multi-GeV region where flavor separated data have been recently made
available. The data show, in particular, a suppression of $d$ quarks with
respect to $u$ quarks at large momentum transfer. %and constant ratios of the
flavor dependent Pauli to Dirac form factors ratios. This trend can be
explained using a reggeized diquark model calculation of generalized parton
distributions, thus providing a correlation between momentum and coordinate
spaces, both of which are necessary in order to interpret the partonic
substructure of the form factors. We extend our discussion to the second
moments of generalized parton distributions which are believed to contribute to
partonic angular momentum.
