Baryon Spectroscopy at COMPASS — •Tobias Weisrock — Institut für Kernphysik, Universität Mainz

The COMPASS 2009 data taking with a 190 GeV/c proton beam impinging on a liquid hydrogen target offers the possibility to study baryon resonances in multiple channels. Complementary to existing data obtained from electro- and photoproduction these hadron-induced reactions can help to complement the known spectrum of baryons.

Only exclusive events will be used for analyses, therefore the recoiling target proton has to be measured using a recoil proton detector. First studies of p_f π⁺π⁻ p_rec, p_f K⁺ K⁻ p_rec and p_f π⁰π⁰ p_rec final states will be presented and an outlook on further analyses given.

Supported by BMBF under the contract 05P12UMCC1 and GRK Symmetry Breaking (DFG/GRK 1581).
