| Research Abstract |
We have carried out the LHCf experiment for measurement of neutral partciles at 0 degree of proton-proton collisions in LHC at 0.9TeV and 7TeV in CMS energy in 2009-2010, which is relevant to air shower development of very high energy cosmic rays. We have reported the first result of experiment for the data of gamma ray energy spectra at 0 degree of 7TeV proton-proton collisions compared with various hadron interaction models relevant to air showers. As the result data looks incompatible with any of existing hadron interaction models completely and suggest possible impact on implication of air shower development.
