Abstract

The latest physics results of LHCf photon analysis are reported in this paper.
The inclusive energy spectrum of photons produced in proton-proton collisions at √s = 13 TeV are shown. The results are compared with the prediction of hadronic interaction models commonly used in air-shower simulations of ultra-high-energy cosmic rays. Even if experimental data lie between the models, there is not a single model consistent with data in all the energy range.
The better overall prediction is given by EPOS-LHC hadronic interaction model.
The electromagnetic energy flow as a function of pseudorapidity is also presented, showing a good agreement of EPOS-LHC and SIBYLL 2.3 models with data.
