Strangeness photoproduction at the BGO-OD experiment

Abstract

The BGO-OD experiment at the University of Bonn's ELSA accelerator facility in Germany is ideally suited to investigate photoproduction at extreme forward angles. It combines a highly segmented BGO electromagnetic calorimeter at central angles and an open dipole magnetic spectrometer in the forward direction. This allows the detection of forward going kaons, and complex final states of mixed charge from hyperon decays. Current projects at the BGO-OD experiment include strangeness production of $\gamma p \rightarrow K^+ \Lambda/\Sigma^0$ at forward angles, $K^0\Sigma^0$ with a deuteron target and $K^+\Lambda(1405)$ line shape and cross section measurements.
