Query: Physics observables for color transparency   The physics observables dedicated to the study of color transparency are
diverse. After a brief pedagogical introduction, we emphasize the
complementarity of the nuclear filtering and color transparency concepts. The
importance of quantum interferences leads to suspect pictures based on the
preparation of a squeezed state of small transverse size leading to a rapid
transverse expansion. The different roles of heavy and light nuclei are
emphasized. The possibility of color transparency tests in the vacuum is
stressed. Such a test may be quickly addressed in the virtual Compton
scattering reactions at CEBAF or HERMES energies.
