Recent Results from the LHCf Experiment
Résumé
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 $\sqrt{s}$ = 7 TeV p–p collisions and the nuclear modification factor for forward neutral pions at $\sqrt{s}$ = 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.
