  The propagation and modification of hard-scattered partons in the QGP can be
studied using various types of jet and jet-like correlation measurements. The
STAR detector with its full azimuthal and large pseudorapidity acceptance, as
well as its wide transverse momentum (pT) coverage, is well-suited for these
measurements. At mid-rapidity, azimuthal correlations of charged hadrons with
the axis of a reconstructed trigger jet are used to study the modification of
jet shapes and associated hadron yields from p+p to Au+Au. Dihadron
correlations with back-to-back high-pT hadron pairs are used to investigate
dijets and fragmentation biases. STAR's increased particle identification
capabilities due to the Time-Of-Flight detector are utilized to investigate the
differences between jet-related and bulk-related particle production. Dihadron
correlations with identified trigger particles provide experimental tests of
simple recombination theories. The comprehensive set of STAR jet-quenching
measurements can be used to further constrain theories of parton energy loss at
RHIC.
