Description
We present a measurement of semi-inclusive recoil jets for both direct-photon and $\pi^{0}$ triggers, within various trigger transverse momentum ($\rm{p_{T}}$) ranges between 9 GeV/c and 30 GeV/c, in central Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV, using 13 $\rm{nb}^{-1}$ of data recorded in the year 2014 by the STAR collaboration. Details of the analysis will be discussed, including correction for the large uncorrelated background contribution to the recoil jet distribution using a mixed-event technique. Finally, we report a comparison between the direct-photon and $\pi^{0}$ triggered recoil jets in central Au+Au collisions and their suppression with respect to p+p collisions and PYTHIA reference for different trigger $\rm{p_{T}}$ ranges.
