Invariant differential cross sections of $\pi^{0}$ and $\eta$ mesons for pp collisions at $\sqrt{s}=8$ TeV. The two-component model (TCM) as well as Tsallis fits to the data are also drawn. Furthermore, the data is compared to the PYTHIA 8.210 Tune 4C and the Monash 2013 tune and recent NLO pQCD calculations, for which details on PDF and FF are given in the figure.
