On the missing momentum dependence of the color transparency effects in (e,e'p) scattering

We explore the missing momentum dependence of the CT effects in quasielastic (e, ep) scattering. We develop the coupled-channel multiplescattering theory (CCMST) description of final-state interaction including both the coherent and incoherent rescatterings of the ejectile state. We demonstrate that the contribution of the off-diagonal incoherent rescattering does not vanish at low Q2 which is a novel correction to the conventional Glauber theory evaluation of nuclear transparency. We comment on the nontrivial impact of this correction on the onset of CT. The sensitivity of the onset of CT to the 3q-nucleon reggeon amplitudes is discussed for the first time. We present numerical results for nuclear transparency as a function of the missing momentum for exclusive (e, ep) reaction in the kinematical region of Q2 ∼ < 40 GeV 2 and pm ∼ < 250 MeV/c.
