abstract = "An invariant differential cross section measurement of inclusive π0 and η meson production at mid-rapidity in pp collisions at s=8 TeV was carried out by the ALICE experiment at the LHC. The spectra of π0 and η mesons were measured in transverse momentum ranges of 0.30 and AESSS for the η overestimate the cross sections of both neutral mesons, although such calculations agree with the measured η/ π0 ratio within uncertainties. The results were also compared with PYTHIA 8.2 predictions for which the Monash 2013 tune yields the best agreement with the measured neutral meson spectra. The measurements confirm a universal behavior of the η/ π0 ratio seen for NA27, PHENIX and ALICE data for pp collisions from s=27.5 GeV to s=8 TeV within experimental uncertainties. A relation between the π0 and η production cross sections for pp collisions at s=8 TeV is given by mT scaling for pT>3.5 GeV/c.

The results were also compared with PYTHIA 8.2 predictions for which the Monash 2013 tune yields the best agreement with the measured neutral meson spectra. The measurements confirm a universal behavior of the η/ π0 ratio seen for NA27, PHENIX and ALICE data for pp collisions from s=27.5 GeV to s=8 TeV within experimental uncertainties. A relation between the π0 and η production cross sections for pp collisions at s=8 TeV is given by mT scaling for pT>3.5 GeV/c.
