Abstract

We have measured the nuclear transparency of the incoherent diffractive A(e, e ^'ρ ⁰) process in ¹²C and ⁵⁶Fe targets relative to ²H using a 5 GeV electron beam. The nuclear transparency, the ratio of the produced ρ ⁰'s on a nucleus relative to deuterium, which is sensitive to ρA interaction, was studied as function of the coherence length (l _c), a lifetime of the hadronic fluctuation of the virtual photon, and the four-momentum transfer squared (Q ²). While the transparency for both ¹²C and ⁵⁶Fe showed no l _c dependence, a significant Q ² dependence was measured, which is consistent with calculations that included the color transparency effects.
