High $p_T$ jet correlations as a probe of the QGP

Angular correlations involving high-$p_T$ particles associated with partonic jet fragmentation provide an important opportunity to study the hot nuclear matter produced in A+A collisions, particularly when compared against a p+p reference. Recent di-jet correlations results suggest that observables characterizing jet shapes in Au+Au and p+p approach comparable values at high $p_T$, leading to questions about experimental accessibility to quenched partons and the nature of medium-induced energy loss. The latest high-$p_T$ di-jet correlations results from the PHENIX experiment will be presented, as well as a discussion of their interpretation.
