Description
Neutral meson production in pp collisions is described by pQCD in a limited kinematic range. Both $\pi^0$ and $\eta$ meson spectra
constrain parameters of theoretical models in both perturbative (NLO, NNLO) and non-perturbative regimes (structure function, fragmentation function). Neutral meson spectra in pp are used as a reference for Pb-Pb and p-Pb measurements at the same per nucleon collision energy. Neutral mesons are also sources of decay photons which are a major background for direct photon measurements. We present the current status of measurements of neutral meson spectra carried out by the ALICE experiment in pp collisions at $\sqrt{s}=5$ TeV with the electromagnetic calorimeter (EMCal) via the invariant mass technique.
