Description
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 coverage, is well-suited for these measurements. Correlations of neutral pions and jet-like clusters at forward rapidity in d+Au collisions are used to probe low x physics and the possible onset of gluon saturation effects. 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. We also show results that take
advantage of STAR's increased particle identification capabilities due
to the Time-Of-Flight detector, such as particle ratios associated with
reconstructed jets, and dihadron correlations with identified trigger
particles. Such measurements will be used to explore the differences
between jet-related and bulk-related particle production. The
comprehensive set of STAR jet-quenching measurements can be used to
further constrain theories of parton energy loss at RHIC.
