abstract
We show effects of the event-by-event fluctuation of the initial conditions (IC) in hydrodynamic description of high-energy nuclear collisions on some observables. Such IC produce not only fluctuations in observables but, due to their bumpy structure, several non-trivial effects appear. They enhance production of isotropically distributed high-pT particles, making v2 smaller there. Also, they reduce v2 in the forward and backward regions where the global matter density is smaller, so where such effects become more efficacious. They may also produce the so-called ridge effect in the two large-pT particle correlation.

An MLE analysis on the relationship between the initial-state granularity and final-state flow factorization
Flow factorization, but not differential flow, responds strongly to initial-state granularity in peripheral-tube hydrodynamic simulations, and MLE and cumulant estimators disagree on these correlators.
