Description
The two component Monte-Carlo Glauber model predicts a knee-like structure in
the centrality dependence of elliptic flow $v_2$ in Uranium+Uranium
collisions at $\sqrt{S_{NN}}=193$ GeV. It also produces a strong anti-correlation
between $v_2$ and $dN_{ch}/dy$ in the case of top ZDC events. However, none
of these features have been observed in data. We address these discrepancies
by including the effect of nucleon shadowing to the two component Monte-Carlo
Glauber model. Apart from addressing successfully the above issues, we find
that the nucleon shadow suppresses the event by event fluctuation of various
quantities, e.g. $\varepsilon_2$ which is in accordance with expectation from
the dynamical models of initial condition based on gluon saturation physics.
