Studies of the muon content of extensive air showers with AMIGA data — •Sarah Müller and Markus Roth for the Pierre Auger collaboration — Karlsruher Institut für Technologie, Karlsruhe, Deutschland

The number of muons in an extensive air shower is an important observable to discriminate between different masses of primary cosmic rays. The engineering array of the AMIGA enhancement (Auger Muons and Infill for the Ground Array) of the Pierre Auger Observatory consists of a hexagon of seven underground muon detectors with 30 m2 surface and 750 m spacing and has been completed in February 2015. We present an analysis of one year of data and compare results with previous muon detection experiments. To construct a fair sample of events, a parametrization of the lateral trigger probability is derived and bias corrections are applied. The muon lateral distribution is parameterized and a comparison to simulations as well as data from other experiments will be shown.
