The LHCf experiment is a double arm sampling calorimeter, installed +/-140 m away from the Atlas LHC interaction point. The detectors allow precise measurement of energy and impact point of the neutral particles (mainly photons and neutrons) produced very forward in the LHC proton-proton interactions, in the pseudorapidity region greater than 8; this measurement is crucial for the calibration of the hadronic interaction models widely used in the High Energy Cosmic Ray field. The experiment has successfully taken data in 2010, at 7 TeV center of mass energy, and it was later on removed to avoid radiation damage once the LHC luminosity was increased. In this talk the main LHCf physics results will be reported, focusing in particular in the single photon energy spectra comparison between experimental data and the expectations of the various models. The upgrade phase, foreseen to reduce the radiation damage effects in the next 14 TeV 2014 center of mass energy run, will also be presented.
