First measurements of Λ and Σ0 hyperons in elementary electroproduction at MAMI
Since 2008 the magnetic spectrometer Kaos, dedicated to the detection of charged kaons, is operating at the 1.5 GeV electron beam of MAMI at the Institut für Kernphysik in Mainz, Germany. The strangeness programme performed in 2008–9 is addressing some important issues in the field of elementary kaon photoelectro-production reactions. The identification of Λ and Σ0 hyperons in the missing mass spectra from kaon production off a liquid hydrogen target demonstrates the capability of the extended facility to perform strangeness electro-production spectroscopy at low momentum transfers Q2<0.5(GeV/c)2. Systematic uncertainties in the cross-section extraction from the data are discussed.
