Abstract (data abstract)
CERN-LHC. The inclusive production rate of neutral pions has been measured by LHCf experiment during sqrt(s)=7 TeV pp collision operation in early 2010. In order to ensure good event reconstruction efficiency, the range of the pi0 rapidity and pT are limited to 8.9 TO 11.0 and pT < 0.6 GeV, respectively.
