Baryon Spectroscopy at COMPASS — •Tobias Weisrock — Institut für Kernphysik, Johannes Gutenberg-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 different channels. These data obtained from hadron-induced reactions are complementary to the ones obtained from electro- and photoproduction due to the different production mechanism.
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 pf π0 prec and pf η prec final states will be presented and an outlook on further analyses given.
