Monte-Carlo studies of the trigger efficiency of the ALICE-PHOS detector — •Alexej Kraiker for the ALICE collaboration — Institut für Kernphysik, Goethe Universität Frankfurt

The ALICE experiment at the LHC investigates the properties of the Quark-Gluon-Plasma (QGP). Various properties of the QGP can be studied by comparing the production of neutral mesons in Pb-Pb and pp collisions.

In ALICE, π0 and η mesons are reconstructed via their two photon decay channel. The decay photons are measured with the calorimeters of the experiment EMCal, DCal and PHOS. In the experiment the measurements of neutral mesons facilitate triggered data to increase the significance of the signal. To normalize the triggered data the trigger efficiency of the trigger needs to be determined.

The poster presents a simulation of the high energy trigger of the PHOS-detector to determine the trigger efficiency. The π0 trigger efficiency is compared with measured data, and predictions for the η mesons trigger efficiency are presented.
