Description

The PANDA experiment will be running up to 2.10^7 antiproton-proton collisions per second at energies reaching 15 GeV. The lack of simple features distinguishing the interesting events from background, as well as strong pileup of events' data streams make the use of a hardware trigger impossible. As a consequence the whole data stream of about 300 GB/s has to be analyzed online, i.e: tracking, vertex finding, particle identification and event building. The GEM Tracker covers polar angles from 4 to 20 degrees in the forward direction, and can be used for the event building in a large fraction of events. In this work the analysis chain and the implemented algorithms will be presented. Moreover, the event builder prototype based on GEM Tracker data will be presented.
