| dc.description | 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 substantial, but uncertain, longitudinal momentum transfer to the nuclear medium. We predict a strong Fermi-momentum bias of the nuclear transparency at high $Q^2$, which enters as a factor at the nuclear spectral function, and makes uncertain the results of measuring the high-momentum tail of Fermi distribution. | |
