The longitudinal asymmetry of the ( e , e ′ p ) missing momentum distribution as a signal of color transparency
We use multiple scattering theory to evaluate the Q 2 dependence of the forward-backward asymmetry, A z , of the missing momentum distribution in quasielstic A(e, e ′ p) scattering, which is expected to be affected by color transparency. The novel features of our analysis are a consistent treatment of the structure of the ejectile state formed after absorption of the virtual photon by the struc...

We develop the Glauber theory description of initial-and final-state interactions (IFSI) in quasielastic A(p, 2p) scattering. We study the IFSI-distortion effects both for the inclusive and exclusive conditions. In inclusive reaction the important new effect is an interaction between the two sets of the trajectories which enter the calculation of IFSI-distorted one-body density matrix for inclu...

Contrary to widespread opinion, color transparency (CT) brings essential ambiguity to, rather than helps in, study of the nuclear spectral function in quasielastic lepton scattering, A(l, l ′ p)A ′ , at high Q 2. Although the nuclear attenuation vanishes, the final state interaction (FSI) of a small-size ejectile wave packet, propagating through nuclear matter, remains. It manifests itself in a...

Do final state interactions obscure short range correlation effects in quasielastic A(e, e ′ p) scattering ? A b s t r a c t Are short range correlations in the ground state of the target nucleus (initial state correlations ISC) observable in experiments on quasielastic A(e, e ′ p) scattering at large missing momentum p m ? Will the missing momentum spectrum observed at CEBAF be overwhelmed by ...

Color transparency is the vanishing of initial and final state interactions, predicted by QCD to occur in high momentum transfer quasielastic nuclear reactions. For specific reactions involving nucleons, the initial and final state interactions are expected to be dominated by exchanges of pions. We argue that these interactions are also suppressed in high momentum transfer nuclear quasielastic ...
