Figure Caption

Isolated photon cross section compared with theory, only the ratio = data / (jetphox * κiso ) is plotted.

NLO calculations scaled down by the partonic to hadronic isolation efficiency κiso

The comparison model is NLO JETPHOX with NNPDOF40 / BFG II FF.

Detail description

Data - LHC12 AOD, MC - GJ + JJhigh.

Shower shape long axis: 0.1 - 0.3. Isolation criteria: Only charged particles in cone size R=0.4 and p_{T}^{iso} < 1.5 GeV/c. 

Model comparison using JETPHOX (NNPDF40 / BFG II FF).
