Measurement of the eta meson with the ALICE PHOS. — •Fabian Pliquett for the ALICE collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt

ALICE as the dedicated heavy ion experiment at the LHC is designed to investigate the properties of the quark gluon plasma. The measurement of the eta meson production complements other measurements of identified particles in the experiment. Collisions of protons with nuclei function as a control experiment to study initial state effects in heavy ion collisions.

The PHOS, one of the electromagnetic calorimeters of the experiment, measures the energy and position of photons with high resolution and therefore allows for the reconstruction of the eta meson by its two-photon decay channel.

The status of the analysis of the eta meson in p-Pb collisions at √s = 5.02 TeV with the ALICE PHOS including peak extraction and acceptance and reconstruction efficiency corrections will be presented.
