Prior to "Quark Matter 2006" predictions within retarded jet absorption scenario at RHIC

Abstract

Predictions for some experimental physical observables in nucleus-nucleus collisions at RHIC energies are presented. I utilize the previous suggestion that the retarded, by time about 2-3 fm/c, jet absorption in opaque core is a natural explanation of many experimental data. This assumption is applied only to the particles with high transverse momentum above 4 GeV/c resulting from parton fragmentation. I calculate nuclear modification factor $R_{AA}$, $R_{AA}$ in- and out of the reaction plane, azimuthal anisotropy parameter $v_2$, jet suppression $I_{AA}$ for the away side jet and its dependence versus the reaction plane orientation. The systems under consideration are Au+Au, Cu+Cu, at 200 GeV and 62 GeV. Most of numbers are predictions prior to the QM2006.
