We present the semi-inclusive measurement of charged jets recoiling fromdirect-photon and $\pi^{0}$ triggers in central Au+Au collisions at$\sqrt{s_{\mathrm {NN}}}$ = 200 GeV, using a dataset with integrated luminosity13 $\mathrm {nb^{-1}}$ recorded by the STAR experiment in 2014. The photon and$\pi^{0}$ triggers are selected within transverse energy ($\rmE_\mathrm{T}^\mathrm{trig}$) between 9 GeV and 20 GeV. Charged jets arereconstructed with the anti-$k_{\mathrm{T}}$ algorithm with resolutionparameters R = 0.2 and 0.5. A Mixed-Event technique developed previously bySTAR is used to correct the recoil jet yield for uncorrelated background,enabling recoil jet measurements over a broad $\rm p_{T,jet}$ range. We reportfully corrected charged-jet yields recoiling from direct-photon and $\pi^{0}$triggers for the above two jet radii and also discuss the jet R dependence ofin-medium parton energy loss at the top RHIC energy.
