Descripción
This paper presents a measurement of jet-track correlations in photon-jet events, using 1.72 nb⁻¹ of Pb + Pb data at √NN = 5.02 TeV recorded with the ATLAS detector at the LHC. Events with energetic photon-jet pairs are selected, where the photon and jet are approximately back-to-back in azimuth. The angular correlation between jets and charged-particle tracks with transverse momentum (pT) in the range 0.5–2.0 GeV in the hemisphere opposite to the jet, |Δ⁢(jet,track)|>/2, is measured as a function of their relative pseudorapidity difference, |Δ⁢(jet,track)|. In central Pb + Pb collisions, these correlations are predicted to be sensitive to the diffusion wake in the quark-gluon plasma resulting from the lost energy of high-pT partons traversing the plasma, with a characteristic modification as a function of |Δ⁢(jet,track)|. The correlations are examined with different selections on the jet-to-photon pT ratio to select events with different degrees of energy loss. No diffusion wake signal is observed within the current sensitivity and upper limits at 95% confidence level on the diffusion wake amplitude are reported.
