Query: Progress in Perturbative Color Transparency   A brief overview of the status of color transparency experiments is
presented. We report on the first complete calculations of color transparency
within a perturbative QCD framework. We also comment on the underlying
factorization method and assumptions. Detailed calculations show that the slope
of the transparency ratio with $Q^2$, and the effective attenuation cross
sections extracted from color transparency experiments depend on the $x$
distribuition of wave functions.
