Quantum color transparency

We propose a quantum description of color transparency in terms of light-cone operator matrix elements. The fundamental quantity needed is the distribution amplitude φA(x,Q²) for each hadron that participates in the elastic scattering in the nuclear target. Two large scales, Q² and a mass scale going like A1/3 for A{}1, occur in a perturbatively consistent description. We find that the limit of large A and moderate Q² may shed light on controversies over the applicability of perturbative QCD to exclusive processes.
