Measurement of transverse momentum spectra of neutral mesons with the ALICE calorimeters — •Adrian Mechler for the ALICE collaboration — Institut für Kernphysik, Goethe Universität Frankfurt, Deutschland

The ALICE experiment at the CERN LHC investigates the properties of the quark-gluon plasma (QGP) which is believed to be produced in Pb--Pb collisions at high collision energies. Hadron production measurements in pp collisions provide information about the underlying QCD processes and fragmentation functions. Furthermore, pp results provide an important baseline for the interpretation of heavy-ion collisions. In ALICE, neutral mesons can be measured via their two-photon decay channel facilitating the ALICE calorimeters EMCal, PHOS and DCal to measure the position and energy of the decay photons.

This talk will discuss measurements of neutral mesons in various collision systems from the recently finished RUN2 data taking period using the ALICE calorimeters. The talk will focus on transverse momentum spectra and their dependence on the different collision systems.
