Study of jet fragmentation via azimuthal correlations: a probe for the sQGP at RHIC

Two particle azimuthal correlation functions are used to study flow and jet fragmentation in the hot QCD matter believed to be created in Au+Au collisions at RHIC (√sNN = 200GeV). Detailed results on jet topologies and yields, and their flavor dependence are obtained via a novel technique for decomposition of the combined correlations from jets and flow in Au+Au collisions. The results indicate significant broadening of the away-side jet attributable to important interactions between the flowing medium and the scattered partons which fragment into jets
