Neutral particles energy spectra for 900 GeV and 7 TeV p-p collisions, measured by the LHCf experiment

LHCf is an experiment designed to study the production in the very forward direction of neutral particles produced in collisions at the LHC. Its results are and will be used to calibrate the hadron interaction models of the Monte Carlo codes which allow the interpretation of energy spectrum and composition of high-energy cosmic rays as measured by air-shower ground detectors. The experiment has already completed data taking in proton-proton collisions at $\sqrt{s} =$ 900 GeV and at $\sqrt{s} =$ 7 TeV during 2009 and 2010. At the beginning of 2013 the experiment will take data again with p-Pb collisions, and then the detectors will be upgraded for the $\sqrt{s} =$ 14 TeV collisions in 2014.
