Measurement of Neutral Mesons in pp Collisions at the LHC with ALICE — •Jens Lühder — Institut für Kernphysik, Münster

In ALICE, the measurement of photons is performed in two different ways: First, via the tracking of e+-e pairs and secondly, via their energy deposits in electromagnetic calorimeters. The first method is called PCM (Photon Conversion Method) as photons may convert to e+-e pairs when interacting with the detector material. For the second method, different calorimeters are used, whereas this talk will focus on the PHOS (PHOton Spectrometer). By using the measured photons to reconstruct the amount of neutral mesons, the fraction of decay photons out of all measured photons can be acquired. The talk will cover the measurement principles of the PCM, the calorimeters and the hybrid method, which combines these two methods in order to benefit from both detection principles. First results of the analysis of neutral mesons in the data of LHC Run 2 with a center of mass energy √s=13 TeV will be given.
