Query: Exploring Skewed Parton Distributions with Two-body Models on the Light
  Front I: bimodality   We explore skewed parton distributions for simple, model wave-functions in a
truncated two-body Fock space. Consideration of non-Gaussian wave functions is
our main emphasis, from which we observe the distributions are bimodal (there
can be two distinct peaks) in the Fock-space diagonal overlap region (x > xi).
We demonstrate that this behavior arises from convoluting two light-front wave
functions to form the skewed parton distribution. Furthermore, the
factorization Ansaetze, which have been used often, are shown not to hold. At
high t, we can write the skewed parton distribution in terms of quark
distribution amplitudes and perturbative wave functions thereby providing new
tests.
