Isolated photons cross section in pp collisions at 8 TeV

Description

Plots for preliminary results on isolated photons cross section measured with the ALICE EMCal in pp collisions at 8 TeV.

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. 

The cross section is compared with NLO JETPHOX calculations with NNPDF40 / BFG II FF, NLO calculations scaled down by the partonic to hadronic isolation efficiency κ^{iso}. The Data/Theory ratio is also shown.

Additionally, the data is compared with W. Vogelsang's NLO calculations with CT18 PDF, GRV FF
