Color Transparency and Color Opacity in Coherent Production of Vector Mesons off Light Nuclei at small x

L. Frankfurt, V. Guzey, W. Koepf +2

Coherent electroproduction of vector mesons off ${}^2$H and ${}^4$He is considered in the kinematics of deep inelastic scattering. Special emphasis is given to the $-t\sim 0.8-1$ GeV$^…
