> Abstract:
> The STAR Collaboration at RHIC reports measurements of
> azimuthal correlations of high transverse momentum ($p_T$) charged
> hadrons in Au+Au collisions at higher $p_T$ than reported previously.
> As $p_T$ is increased, a narrow, back-to-back peak emerges above the
> decreasing background, providing a clear dijet signal for all collision
> centralities studied.  Using these correlations, we perform a systematic
> study of dijet production and suppression in nuclear collisions,
> providing new constraints on the mechanisms underlying partonic energy
> loss in dense matter.
