Recent Results from the LHCf Experiment

Abstract

The LHCf experiment is an unique dedicated experiment for measurement of very forward particle production relevant to cosmic-ray air shower developments. The LHCf measured the spectra for forward photons, neutral pions and neutrons at √ s = 7 TeV p-p collisions and the nuclear modification factor for forward neutral pions at √ s = 5 TeV p-Pb. No hadronic interaction models used in air shower developments of very high energy cosmic-rays is able to reproduce all LHCf data reasonably while some of models are able to reproduce LHCf data partially.
