THE FERMI-MOTION EFFECT IN THE SIGNAL FOR COLOR TRANSPARENCY IN (E, E' P) SCATTERING

The signal for color transparency depends on the composition and intra nuclear rescattering of the ejectile wave packet emerging from the har d ep vertex. The electron scattering kinematics, in conjunction with t he Fermi motion of bound nucleons, allows one to control the compositi on of the ejectile wave packet. Using the diffraction operator techniq ue developed by us recently we derive the dependence of the color tran sparency signal on the Bjorken variable x of the scattered electron. T he Fermi-motion bias is found to be much weaker than has been claimed recently.
