  4. 2. Two-pion production in proton-proton collisions near threshold

    Author : Jan Johanson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; Meson production near threshold; Two-pion production; Strålningsvetenskap; Radiation biology; Strålningsbiologi; Nuclear Physics; kärnfysik;

    Abstract : Two-pion production reactions in proton-proton collisions have been studied using the PROMICE/WASA detector and an internal cluster gas-jet target at the CELSIUS storage ring in Uppsala. Three out of the four isospin-independent reaction channels have been measured at several energies in the intermediate and near threshold energy region. READ MORE
