Neutral Meson Production in pp and p-Pb Collisions Measured with ALICE Calorimeters — •Fabian Pliquett for the ALICE collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt

The properties of the quark-gluon plasma, a hot and dense state of matter created in high-energy nucleus-nucleus collisions, are investigated by ALICE, the dedicated heavy-ion experiment at the LHC, by means of particle production measurements. At high transverse momentum they provide information on the energy-loss mechanism of partons in the plasma. The measurement of neutral meson production complements other measurements of identified particles in the experiment. pp and p-Pb collisions function as control experiments to facilitate a better understanding of particle production in heavy-ion collisions. In ALICE, the reconstruction of neutral mesons is conducted by measuring the energy and position of the decay photons from the two-photon decay channel.

In this talk, the status of the neutral-meson measurements in pp and p-Pb collisions with two of the ALICE calorimeters, PHOS and EMCal, will be presented.
