The LHCf experiment is designed to provide precise measurements of the production spectra relative to neutral particles produced in the very forward region by high energy proton-proton and proton-ion collisions. This information is necessary in order to test and tune hadronic interaction models used by ground-based cosmic rays experiments. In order to reach this goal, LHCf makes use of two small sampling calorimeters installed in the LHC tunnel at ±140 m from IP1, both able to detect neutral particles having pseudo-rapidity η > 8.4. In LHC Run II, LHCf acquired data relative to p-p collisions at √s = 13 TeV and p-Pb collisions at √sNN = 8.1 TeV. In this paper, we discuss the results obtained from p-p collisions at √s = 13 TeV, focusing in particular on photon and neutron production, the two analyses already published by the collaboration.
