Energy and system size dependence of subnucleonic fluctuations

Toward the energy and the system size dependence of ellip- tic flow: working on flow fluctuations

In this talk I concentrate on two topics closely related to the understanding of the energy and the system size dependence of the elliptic flow: determination of the elliptic flow (v2) “free” from the effects of non-flow and flow fluctuations, and the role of fluctuations in the initial eccentricity of the overlap region. I introduce a new approach for the analysis of the distribution in flow v...

Beam-energy and system-size dependence of dynamical net charge fluctuations

Beam-Energy and System-Size Dependence of Dynamical Net Charge Fluctuations

We present measurements of net charge fluctuations in Au + Au collisions at √ sNN = 19.6, 62.4, 130, and 200 GeV, Cu + Cu collisions at √ sNN = 62.4, 200 GeV, and p + p collisions at √ s = 200 GeV using the net charge dynamical fluctuations measure ν+−,dyn. The dynamical fluctuations are non-zero at all energies and exhibit a rather modest dependence on beam energy. We find that at a given ener...

Energy and System Size Dependence of Charged Hadron

The PHOBOS collaboration has measured transverse momentum distributions of charged hadrons produced in Cu+Cu collisions at √ s NN = 200 and 62.4 GeV. The nuclear modification factor R N part AA is calculated relative to p+p data at both collision energies as a function of collision centrality. For the same number of participating nucleons, R N part AA is essentially the same in both systems ove...
