Description
Colliding nuclei consist of nucleons with a shifted scale, which makes such a medium more opaque for dipoles. Therefore J/Psi will be more suppressed than predicts a simple extrapolation from pA to AA. Another effect is an enhanced color transparency. A ccbar dipole propagates simultaneously through both colliding nuclei. Due to color filtering one nucleus absorbs dipoles of larger size, and this make the other nucleus more transparent (compared with that in pA) for such
small dipoles which survived in the first nucleus.
