Description
We report the semi-inclusive distribution of fully-reconstructed jets
recoiling from a direct photon trigger in p+p and central Au+Au collisions
at √sN N = 200 GeV. This observable provides an incisive probe of the
Quark-Gluon Plasma generated in high-energy nuclear collisions. Direct
photons are measured using the STAR Barrel Electromagnetic Calorime-
ter (BEMC). Jet reconstruction is carried out by the anti-kT algorithm
with jet resolution parameters R=0.2 and R=0.5, utilizing neutral energy
measured in the BEMC and charged-particle tracks. Uncorrelated jet
background is mitigated using event mixing. This measurement extends
a recently reported STAR measurement of the same observable, which
used charged-particle jets, to fully-reconstructed recoil jets. The status of
the analysis will be reported, and its physics prospects will be discussed.
