Using CMBR tools for flow anisotropies in relativistic heavy-ion collisions

Abstract

Recently we have shown that there are crucial similarities in the physics of cosmic microwave background radiation (CMBR) and relativistic heavy-ion collision experiments (RHICE). We have argued that following CMB analysis technique, a plot of the root mean square value of the flow coefficient vñrms calculated in lab fixed frame will give important information about the initial state fluctuations and also can be used to directly probe elliptic flow in non-central collisions. Here we demonstrate how following the analysis techniques used in CMBR can give important information about the initial state and evolution of the plasma formed in heavy ion collisions. We further explore the similarities in the physics of CMB and RHICE by studying the effect of large magnetic field on flow coefficients. © 2011 Elsevier B.V.
