QCD observables in (e,e'p) scattering on nuclei in the colour transparency regime
Nikolaev N.N.
I demonstrate that a transverse size of the ejectile state emerging from the quasielastic e+p scattering on nuclei does not decrease with the momentum transfer Q. None the less, a strength of nuclear attenuation vanishes with Q, and I identify the QCD mechanism of vanishing attenuation (colour transparency). Strong correlation between the onset of colour transparency regime and the asymptotic behaviour of charge form factors is found. Colour transparency regime is elusive up to very large Q.
