Isolated photon cross-section and the theory results as function of gamma pT.

The comparison model is NLO JETPHOX calculation with NNPDOF40, NLO calculations scaled down by the partonic to hadronic isolation efficiency κiso, and NLO calculations (CT18 PDF, GRV FF) from Werner Vogelsang.

Detail description

Using the LHC16,17,18 AOD dataset (MB, G2, G1) and corresponding simulation (GJ, JJlow, JJhigh, JJveryhigh) sample. the analysis used detector is EMCal and DCal. Gamma select shower shape cut is [ 0.1, 0.3 ]. Only consider charge particle in isolation cone and the isolation cut is cone size R=0.4 and pTiso < 1.5 GeV/c
