Generalized Parton Distributions of the Photon in Position Space
  We report on a calculation of the generalized parton distributions of the photon when there is non-zero momentum transfer both in the transverse and longitudinal directions. By taking Fourier transforms of the GPDs with respect transverse and longitudinal momentum transfer, we obtain the parton distributions of the photon in position space.
