Abstract
- Neutral pion and $\eta $ meson invariant differential yields were measured in non-single diffractive p–Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV with the ALICE experiment at the CERN LHC. The analysis combines results from three complementary photon measurements, utilizing the PHOS and EMCal calorimeters and the Photon Conversion Method. The invariant differential yields of $\pi ^{0}$ and $\eta $ meson inclusive production are measured near mid-rapidity in a broad transverse momentum range of $0.3 4 $\hbox {GeV}/c$ at $0.483 \pm 0.015_{\mathrm{stat}} \pm 0.015_{\mathrm{sys}}$ . A deviation from $m_{\mathrm{T}}$ scaling is observed for $p_{\mathrm{T}}
