   Abstract:
   Exclusive incoherent electroproduction of the ρ⁰(770) meson from ¹H, ²H, ³He, and ¹⁴N targets has been studied by the HERMES experiment at squared four-momentum transfer Q² > 0.4GeV² and positron energy loss v from 9 to 20 GeV. The ratio of the ¹⁴N to ¹H cross sections per nucleon, known as the nuclear transparency, was found to decrease with increasing coherence length of quark-antiquark fluctuations of the virtual photon. The data provide clear evidence of the interaction of the quark-antiquark fluctuations with the nuclear medium. © 1999 The American Physical Society.
