Description
In this talk we report measurements by the STAR collaboration
of the semi-inclusive yield and azimuthal distribution of
reconstructed charged jets recoiling from a high p_{T} hadron
trigger, in central and peripheral Au+Au collisions at \sqrt{s_{NN}} = 200 GeV. Corrections
for the large underlying background to jet observables in
heavy-ion collisions are carried out on an ensemble-averaged
basis using a novel event-mixing technique, without imposition of a
fragmentation bias on the reported jet population. Charged recoil jets
with a transverse momentum up to 34 GeV/c are reported without a
low-p_{T} cutoff, for jet radii up to R=0.5. We compare the
measurements to theoretical calculations and to similar jet
measurements at the LHC. These measurements provide insight into the
nature of jet quenching, and may probe the quasi-particle degrees of
freedom in the Quark-Gluon Plasma.
