Data analysis with the BGO-OD experiment — •Thomas Jude — Physikalisches Institute, Universität Bonn

The new BGO-OD experiment at the ELSA accelerator facility, Bonn, consists of the highly segmented BGO calorimeter with a particle tracking magnetic spectrometer at forward angles. This allows the investigation of final states of mixed charge with nearly 4π acceptance, with very high precision at forward angles for charged particles. An extensive physics programme using an energy tagged bremsstrahlung photon beam is employing this unique setup, with measurements planned for associated strangeness, vector meson and pseudoscaler meson photoproduction.

Analysis of data from the first data taking beam time, and comparison with simulated data is presented. This includes particle momentum reconstruction with the BGO and the forward spectrometer. Highlights include a new method of K⁺ identification via the time delayed decay in the BGO crystals, greatly increasing the acceptance region for K⁺ and vector mesons.
