Study of hadronic jet shape modification in hot QCD matter with the PHENIX detector at RHIC

It is a well established fact now that the hot QCD medium formed in central AuAu collisions at $\sqrt{s_{NN}} = 200$ GeV at RHIC suppresses the high transverse momentum hadrons from jets by inducing gluon radiation. Preliminary results on the angular distribution of hadrons within jets obtained via di-hadron correlations also show strong modifications of jet shapes due to the interaction with this medium. We present a high precision study of hadronic jet shape parameters in AuAu collisions with the di-hadron azimuthal correlation method in the intermediate (1-7GeV/c) transverse momentum region.
