Hi, Michael, > centrality. This effect is consistent with a reduction in the > number of gluons at small Feynman x, possibly caused by gluon fusion. I think gluon fusion is not a necessary condition for saturation. Let me quote an "explanation" from one of Raju Venugopalan's earlier papers. "Consequences of parton "overcrowding" are that two soft partons MAY recombine to form a harder parton OR a parton may be screened by a cloud of surrounding wee partons. These processes inhibit the growth of parton distributions which saturate at some critical x."
