Publication Abstract: The color transparency phenomenon refers to the suppression of final-state interactions of a hadron propagating through the nuclear medium at large momentum transfer when the hadron is produced with small transverse size. The pion electroproduction cross section from ¹H, ²H, ¹²C, ?³Cu and ¹?³Au targets from Q² = 1.1 to 4.8 (GeV/c)² was measured in Jefferson Laboratory Experiment E01-107. The nuclear transparency was formed by the ratio of (?A/?H) from a model of electroproduction from nuclei that does not include ?-N final state interactions. A signature of color transparency is the enhancement of the nuclear transparency at large Q² compared with predictions based on Glauber multiple scattering theory. This experiment represents the first nuclear transparency data from (e,e',?+) reactions.
