Initial condition from the shadowed Glauber model

Initial condition from the shadowed Glauber model

The two component Monte-Carlo Glauber model predicts a knee-like structure in the centrality dependence of elliptic flow v2 in Uranium + Uranium collisions at sNN=193 GeV. It also produces a strong anti-correlation between v2 and dNch/dy in the case of top ZDC events. However, none of these features...
