Abstract

The γp→K0Σ+ reaction has been measured from threshold to Eγ=1.45 GeV (WCM=1.9 GeV) using the Crystal Ball and TAPS multiphoton spectrometers together with the photon tagging facility at the Mainz Microtron MAMI. In the present experiment, this reaction was searched for in the 3π0p final state, by assuming K0S→π0π0 and Σ+→π0p. The experimental results include total and differential cross sections as well as the polarization of the recoil hyperon. The new data significantly improve empirical knowledge about the γp→K0Σ+ reaction in the measured energy range. The results are compared to previous measurements and model predictions. It is demonstrated that adding the present γp→K0Σ+ results to existing data allowed a better description of this reaction with various models.
