Abstract
At the electron accelerator facility ELSA of the University of Bonn the photoproduction reaction γp → K0Σ+ was investigated using the CBELSA/TAPS experimental setup. A pronounced structure in the cross section is found at the K* threshold. It is speculated whether this is due to the formation of a K* -hyperon quasibound state below the K* threshold. The impact of recent polarisation measurements is discussed.
