Description
Uncertainty in the hadronic interaction models is one of the most important sources
of the difficulty to interpret cosmic-ray air shower data. Large Hadron Collider at CERN can provide the best opportunity to test and improve the models at the maximum laboratory energy of 10^17eV. In this talk, some key observations from the LHC experiments are reviewed. Among them detail of a dedicated experiment motivated for the cosmic-ray physics, LHC forward (LHCf), will be presented. The results from the 900GeV and 7TeV proton-proton collisions are presented together with a short introduction of the experiment and on going and future plans.
