STAR: Jet reconstruction, direct γ and multi-hadron correlations

Recent results from the STAR collaboration focusing on hard probes of the initial and final state are presented. Correlations at forward rapidities in d+Au collisions at low x are utilized to study the possible onset of saturation effects at RHIC energies. Reference measurements of fully reconstructed jets in d+Au collisions as well as jet quantities in p+p collisions will be discussed. In addition, jet-hadron, direct γ-hadron correlations and results from full-jet reconstruction in Au+Au collisions will be presented and discussed with respect to the p+p reference measurements. These measurements can be used to put further constraints on the underlying mechanisms of partonic energy loss in heavy-ion collisions at RHIC.
