Investigation of the a0(980)/f0(980)-resonances with ANKE at COSY* — •Alexey Dzyuba1, Markus Büscher2, Vera Kleber3, and Vladimir Koptev11Petersburg Nuclear Physics Institut, Gatchina, Russia — 2Institut für Kernphysik, Forschungszentrum Jülich — 3Institut für Kernphysik, Universität zu Köln

The production of the lightest scalar resonances a0(980) and f0(980) in hadronic interaction is being investigated with the ANKE spectrometer, where their decays into KK can be observed. Final goal of these studies, which will be later supplemented by measurements of the non-strange decays with the WASA detector, is to learn about the nature of these states, about isospin violating processes in the a0/f0 system, FSI effects between antikaons and light nuclei. In this talk results of the data analysis for the reaction ppda0+dK+K^0 measured at a beam energy Tp=2.83 GeV will be presented. Total cross-sections, invariant-mass and angular distributions will be shown and compared with theoretical predictions. Preliminary results from our beam times aiming at a0/f0 production in the reactions pnda00/f0dK+K and dd→ α f0→α K+K will also be discussed. * supported by FZJ, DFG, BMBF, RFFI
