Like sign pion femtoscopy with HADES — •Barbara Schweisshelm for the HADES collaboration — Physik Department, TUM, Garching, Germany — Excellence Cluster "Universe", Garching, Germany

The results of a three dimensional correlation analysis for like sign pion pairs, which are produced in π- + W reactions at 1.7GeV/c at HADES, are presented. Different PID cuts allow the identification of like sign pion pairs, which are used to investigate the correlation between these pairs. In particular the size of the source of the pair can be determined after applying some corrections, which take e.g. the resolution of the detector into account. The analysis was performed in a longitudinally co-moving system to reveal differences of the source size for different emission directions.
