In the framework of the hadron program of COMPASS, the successful candidate will take part in the development of a partial wave analysis tool which will allow for the identification of hadronic resonances and the determination of their quantum numbers. The partial wave analysis is the essential ingredient for the identification of any exotic hadronic states like hybrids and glue-balls. This work is part of the preparation of the 2007 run of COMPASS, when COMPASS will focus on the search of "exotics" in pp-interaction (central production). Nevertheless, the principals of the analysis and the software tools can be tested with already existing data on exclusively measured reactions from earlier beam times with pion and muon beams as well as with event generators. The difficulties of the task can be adapted to the skills of the candidate.
