Description

We study dependence of jet quenching on matter density, using 'tomography' of the fireball provided by RHIC data on azimuthal anisotropy v2 of high pt hadron yield at different centralities. Slicing the fireball into shells with constant (entropy) density, we derive a 'layer-wise geometrical limit' v2max which is indeed above the data v2Tc. One possible reason for such enhancement may be recent indications that the near-Tc region is a magnetic plasma of relatively light color-magnetic monopoles.
