ISI gluon saturation (“CGC”) models vs. data

• Caveat: High pT at midrapidity at RHIC is above Qs ~ 1-2 GeV/c (straight application of CGC questionable in first instance).

• Magnitude of Au+Au suppression  saturated Au wave function (Kharzeev et al.). But: no suppression expected by Baier et al.
• Centrality dependence of Au+Au suppression  Npart scaling -like observed (modulo quantitative details).
• Some deficit expected in d+Au collisions (Kharzeev et al.).
• d+Au Cronin enhancement built in the initial wave function (Baier et al.). Similar conclusions by J.Jalilian too (though no calculations at y = 0).
• Somewhat confusing interpretation of Au+Au, d+Au results.
• More converging agreement needed between diff. calculations ...
• (in any case, they seem to describe either Au+Au or d+Au
• observations, but not both at once)
