Abstract (data abstract)
CERN-LHC. The transverse momentum distribution for inclusive neutral pions in the very forward rapidity region has been measured with the LHCf detector. Given the geometrical acceptance of the LHCf detector and to ensure a good event reconstruction efficiency, the rapidity and pT range of the pi0s are limited to -11.0 < ylab < -8.9 and pT < 0.6 GeV, respectively.
