In this paper, we report the production cross-section of forward photons in the pseudorapidity regions of and , measured by the LHCf experiment with proton–proton collisions at . The results from the analysis of of data obtained in June 2015 are compared to the predictions of several hadronic interaction models that are used in air-shower simulations for ultra-high-energy cosmic rays. Although none of the models agree perfectly with the data, EPOS-LHC shows the best agreement with the experimental data among the models.
