Description
Jet quenching arises from jet-medium interactions in the Quark-Gluon Plasma (QGP) created in high-energy collisions of large nuclei, such as Au or Pb nuclei. The study of jet quenching in small systems, e.g. proton-nucleus collisions, has generated great interest in the community due to its relatively smaller initial energy density, temperature, and size of the created medium. Isobar collisions ($\rm Ru^{44}_{96}$+$\rm Ru^{44}_{96}$ and $\rm Zr^{40}_{96}$+$\rm Zr^{40}_{96}$) at RHIC can similarly be used to study jet quenching in systems that are intermediate in size compared to the ones mentioned above. Previously, semi-inclusive distributions of charged-particle jets recoiling from a high transverse-momentum hadron trigger (h+jet) in $\rm Au$+$\rm Au$ collisions at $\sqrt {s_{\rm NN}}=$ 200 GeV at RHIC have been reported, and show a suppression in central relative to peripheral events. Utilizing the same mixed-event technique to correct for uncorrelated combinatorial background present in heavy-ion collisions, we will present our preliminary measurements of uncorrected semi-inclusive h+jet for different jet radii using anti-k$_{T}$ jet reconstruction algorithm in these isobar collisions.
