Jet Measurements with Neutral and Di-jet Triggers in Central Au + Au Collisions at sNN=200Â GeV with STAR

We present two measurements related to jet production in p+p and central Au+Au collisions at sNN=200 GeV. Firstly, a study of semi-inclusive charged recoil jets coincident with high-pT direct-photon and neutral pions, and secondly, the hadron correlations with respect to reconstructed di-jet triggers. Indication of medium effects is observed by comparing γ+jet and π0+jet measurements. The di-jet+hadron study shows signs that the medium-induced modifications of an imbalanced set of di-jets with “hard cores” primarily affect the recoil jet.
