The first evidence of jet quenching was observed at RHIC via suppression of single high $p_T$ hadron $R_{AA}$ and the disappearance of the away-side jet peak in two-particle correlations. Since then, hadron $R_{AA}$ and two-particle…
This is a status report on where PHENIX stands in terms of mapping out the landscape of jet correlation in $p_T$, hadron species, $\sqrt{s}$. We discuss separately high $p_T$ correlation results and low and intermediate $p_T$ correlation…
A selected set of di-hadron correlation results from PHENIX are discussed. These results provide evidences for four distinct contributions concentrated at various $\Delta\phi$ ranges. The $p_T$, particle species and energy dependence of…
Fully reconstructed jets and direct photon-tagged jet fragments significantly reduce energy-loss bias, the bias toward mostly measuring particles from partons which suffer little energy loss. In d+Au collisions, one accesses the physics at…

High P_T measurements of hard hadrons or jets at RHIC and LHC appear contradictory and in some cases counter-intuitive, but upon closer investigation they represent a coherent picture of jet-medium interaction physics which can be…
