ELLIPTIC FLOW, INITIAL ECCENTRICITY AND ELLIPTIC FLOW FLUCTUATIONS IN HEAVY ION COLLISIONS AT RHIC.
Abstract
We present measurements of elliptic flow and eventbyevent fluctuations established by the PHOBOS experiment. Elliptic flow scaled by participant eccentricity is found to be similar for both systems when collisions with the same number of participants or the same particle area density are compared. The agreement of elliptic flow between Au+Au and Cu+Cu collisions provides evidence that the matter is created in the initial stage of relativistic heavy ion collisions with transverse granularity similar to that of the participant nucleons. The eventbyevent fluctuation results reveal that the initial collision geometry is translated into the final state azimuthal particle distribution, leading to an eventbyevent proportionality between the observed elliptic flow and initial eccentricity.

We study effects of eccentricity fluctuations on the elliptic flow coefficient v{sub 2} at midrapidity in both Au+Au and Cu+Cu collisions at {radical}(s{sub NN})=200 GeV by using a hybrid model that combines ideal hydrodynamics for spacetime evolution of the quark gluon plasma phase and a hadronic transport model for the hadronic matter. For initial conditions in hydrodynamic simulations, both the Glauber model and the color glass condensate model are employed to demonstrate the effect of initial eccentricity fluctuations originating from the nucleon position inside a colliding nucleus. The effect of eccentricity fluctuations is modest in semicentral Au+Au collisions, but significantlymore »

Effects of fluctuations on the initial eccentricity from the color glass condensate in heavy ion collisions
We introduce a modified form of the KharzeevLevinNardi (KLN) approach for nuclear collisions. The new ansatz for the unintegrated gluon distribution function preserves factorization, and the saturation scale is bound from below by that for a single nucleon. It also reproduces the correct scaling with the number of collisions at high transverse momentum. The corresponding Monte Carlo implementation allows us to account for fluctuations of the hard sources (nucleons) in the transverse plane. We compute various definitions of the eccentricity within the new approach, which are relevant for the interpretation of the elliptic flow. Our approach predicts breaking of themore » 
Method for determining eventbyevent elliptic flow fluctuations based on the firstorder event plane in heavyion collisions
A new method is presented for determining eventbyevent fluctuations of elliptic flow, v{sub 2}, using firstorder event planes. By studying the eventbyevent distributions of v{sub 2} observables and firstorder eventplane observables, average flow <v{sub 2}> and eventbyevent flow fluctuations can be separately determined, making appropriate allowance for the effects of finite multiplicity and nonflow. The method has been tested with Monte Carlo simulations. The connection between flow fluctuations and fluctuations of the initialstate participant eccentricity is discussed. 
Elliptic flow fluctuations in heavy ion collisions and the perfect fluid hypothesis
We analyze the recently measured v{sub 2} fluctuation in the context of establishing the degree of fluidity of the matter produced in heavy ion collisions. We argue that flow observables within systems with a nonnegligible mean free path should acquire a 'dynamical' fluctuation, due to the random nature of each collision between the system's degrees of freedom. Because of this, v{sub 2} fluctuations can be used to estimate the Knudsen number of the system produced at the Relativistic Heavy Ion Collider (RHIC). To illustrate this quantitatively, we apply the UrQMD model, with scaled cross sections, to show that collisions atmore » 
Determining initialstate fluctuations from flow measurements in heavyion collisions
We present a number of independent flow observables that can be measured using multiparticle azimuthal correlations in heavyion collisions. Some of these observables are already well known, such as v{sub 2}(2) and v{sub 2}(4), but most are newin particular, joint correlations among v{sub 1}, v{sub 2}, and v{sub 3}. Taken together, these measurements will allow for a more precise determination of the medium properties than is currently possible. In particular, by taking ratios of these observables, we construct quantities that are less sensitive to the hydrodynamic response of the medium and thus more directly characterize the initialstate fluctuations of themore »
