Query: Leading Chiral Corrections to the Nucleon Generalized Parton
  Distributions   Using heavy baryon chiral perturbation theory we study the leading chiral
corrections to the complete set of nucleon generalized parton distributions
(GPDs). We compute the leading quark mass and momentum transfer dependence of
the moments of nucleon GPDs through the nucleon off-forward twist-2 matrix
elements. These results are then applied to get insight on the GPDs and their
impact parameter space distributions.
