Measurement of In-Medium Jet Modification Using Direct Photon plus Jet and π0 + Jet Correlations in p + p and Central Au plus Au Collisions at root sNN=200 GeV
Original language description
The STAR Collaboration presents measurements of the semi-inclusive distribution of charged-particle jets recoiling from energetic direct-photon (gamma(dir)) and neutral-pion (pi(0)) triggers in p + p and central Au + Au collisions at root s(NN) = 200 GeV over a broad kinematic range, for jet resolution parameters R = 0.2 and 0.5. Medium-induced jet yield suppression is observed to be larger for R = 0.2 than for 0.5, reflecting the angular range of jet energy redistribution due to quenching. The predictions of model calculations incorporating jet quenching are not fully consistent with the observations. These results provide new insight into the physical origins of jet quenching.
