摘要:

An approved and funded exclusive COSY experiment is presented, which focuses on near threshold two meson production via the reactionsp+d→3He+&pgr;+&pgr;−andp+d→3 He+K+K−. It takes advantage of the high quality of the cooled external COSY beam and the existing spectrometer BIG KARL. The setup consists of a vertex wall and a scintillator cylinder and endcap covering a 4&pgr; solid angle. The large efficiency and high resolution of this detection method will yield precision data on the low energy (T<50 MeV) meson‐meson interaction and probe into questions like the ABC‐effect and KK&dundot; molecule. The detector further allows a measurement of possible radiative &fgr; (1020) decay, which will directly probe the strange quark content of thef0(975). Existing inclusive data as well as first results of a very recent ‘semi‐exclusive’ experiment performed at SATURNE will be also be presented.
