抄録

The LHCf experiment is an unique dedicated experiment for measurement of very forward particle production relevant to cosmic-ray air shower developments by using small electromagnetic imaging calorimeters at the zero degree of the LHC interaction point, IP1. The operationa with p-p collisions at s = 900 GeV and 7 TeV have been done in 2009 and 2010. The results of forward production spectra of photons and π⁰s are compared with the existing cosmic ray interaction models, SYBILL, QGSJETII, DPMJET3, and EPOS1.99. None of them could completely reproduce the data. On-going hadron analysis will be also important to understand inelas-ticity of collisions. LHCf has also completed data taking for LHC p-Pb collisions to study nuclear effect relevant to air shower development. This is also very important to validate composition measurements by air-shower experiments based on X_MAX. Current achievement of the LHCf experiment and possible future experiments at p-A and/or A-A collisions at LHC and RHIC are presented.
