متن کاملInvestigation of the Charge Symmetry conserving reaction dd → 3Henπ0 with WASA-at-COSY
The reaction dd → 3Henπ0 has been measured at a beam momentum of pd = 1.2 GeV/c using the WASA-at-COSY facility. For the first time data on the total cross section as well as differential distributions were obtained. The data are described with a phenomenological approach based on the combination of a quasi-free model and a partial wave expansion model for the three-body reaction.
متن کاملThe WASA Detector Facility at CELSIUS
The WASA 4π multidetector system, aimed at investigating light meson production in light ion collisions and η meson rare decays at the CELSIUS storage ring in Uppsala is presented. A detailed description of the design, together with the anticipated and achieved performance parameters are given.
متن کاملsubmitted to acta physica slovaca 1 – 6 WASA at COSY
The Wide Angle Shower Apparatus (WASA) has been transferred from the storage ring CELSIUS (TSL, Uppsala, Sweden) to the cooler synchrotron COSY (FZ Jülich, Germany). In this presentation, the status and planning of the WASAatCOSY project are reported. The main physics aspects are rare decays of η and η' mesons and isospin violation in deuteron-deuteron interactions.
متن کاملSearch for Η-mesic Helium Using the Wasa-at-cosy Detector
We conduct a search for the He − η bound state with the WASAat-COSY facility via the measurement of the excitation function for the reaction dd → He p π−. In first experiment performed in June 2008, we used COSY deuteron beam with a slowly ramped beam momentum corresponding to a variation of the excess energy for the Heη system from -51.4 MeV to 22 MeV. Here we report on the status of the measu...
