Possible evidence for color transparency from dijet production with   large rapidity gaps in $\gamma p$ scattering at HERA and how to test it in   $\gamma p, \gamma A$ scattering
  We argue that the probability of gap survival in dijet production in $\gamma p$ scattering as measured by ZEUS may be due to the color transparency phenomenon and suggest ways to test this hypothesis in the future $\gamma p$ and $\gamma A$ processes.
