Description

We propose to measure the cross section of the reaction pp → da0+ → dK+ anti K0 and the mass spectra of the K+ anti K0 system at energies Tp=2.52..2.60 GeV at COSY using the ANKE spectrometer and a frozen-pellet target. Within approx. one week of beam time we intend to collect a few thousand events of a0+ decays into K+ anti K0 at different energies between 2.52 and 2.60 GeV. The results will help to clarify whether the a0+ is a real resonance or a K+ anti K0 threshold cusp. (orig.)
