    Abstract

    The LHCf experiment is an LHC forward experiment dedicated to high energy cosmic-ray physics. The LHCf has completed the first phase of physics program, data taking at √s=900 GeV and 7 TeV proton-proton collisions, in July 2010. The LHCf detectors have capability of measurement of forward π0 with more than 600 GeV by reconstruction from photon pairs measured by the two calorimeter towers. A data set taken by the Arm2 detector in 15 May 2010 was analyzed. In this paper, the measured π0 energy spectrum is presented.
