The collective flow of the system plays a critical role in establishing the equation of state for QGP. Among the different orders of azimuthal flow, the second order elliptic flow (v_2) has received much attention, and will be analyzed in the ultra-central collision (0-5%) centrality range. Various hydrodynamic simulations show that v_2 correlates almost linearly with the initial eccentricity ε_2 of the system (which fluctuates on an event by event basis). Measurements of v_2 fluctuations are extremely sensitive to the initial state configuration. An unfolding method has been used to obtain the underlying v_2 distributions from Pb-Pb collisions with a center of mass energy per nucleon of 2.76 TeV.application/pdfengThe author of this work is the copyright owner.
