We present selected recent results of multi-hadron correlation measurements in azimuth and pseudorapidity at intermediate and high \pt{} in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV, from the STAR experiment at RHIC. At intermediate \pt,…

Di-hadron correlation measurements have been used to probe di-jet production in collisions at RHIC. A strong suppression of the away-side high-pT yield in these measurements is direct evidence that high-pT partons lose energy as they…

We explore jet-medium interactions via the recently developed multi-hadron correlation or "2+1" technique. We restrict the di-jet kinematics by selecting a pair of approximately back-to-back high pT hadron triggers and study associated…

Azimuthal correlation functions are used to study jet- and di-jet properties as a function of centrality in Au+Au collisions at $\sqrt{s_{_{\rm NN}}}$=200 GeV. Utilizing a novel technique to decompose the correlation function into a…
