Neutral Meson Production Results in $${pp}$$, $${p}$$–Pb and Pb–Pb Collisions in ALICE

In high-energy hadronic collisions neutral meson spectra can be measured with high precision in a wide range of transverse momenta, providing valuable input for the nucleon structure functions parametrization and for studying in great detail the cold and hot matter effects. The main decay modes of neutral mesons include photons in the final state. The ALICE experiment at the LHC provides the possibility to measure photons in large acceptance EMCAL or precise PHOS calorimeters and to reconstruct photons converted in $$e^{+}e^{-}$$ pairs in the central barrel tracking system. Simultaneous measurement of neutral meson spectra with different methods provides good cross-check of the measurements and allows one to dramatically reduce uncertainties. We present recent results from ALICE on the neutral meson measurements in $$pp$$ , $$p$$ –Pb, and Pb–Pb collisions at LHC energies based on the data collected in LHC Run 2 and the performance of ALICE in LHC Run 3.
