Abstract

The cross-sections of the pd →³He π⁰π⁰π⁰ and pd→³Heπ⁺π^-π⁰ reactions have been measured at the beam kinetic energies T_p= 1360 MeV and T_p= 1450 MeV using the CELSIUS/WASA detector setup. At both energies, the differential cross-section dσ/dω of the η meson in the pd →³He η reaction shows a strong forward-backward asymmetry in the CMS. The ratio between the pd→³Heπ⁺π^-π⁰ and pd→³Heπ⁰π⁰π⁰ cross-sections has been analysed in terms of isospin amplitudes. The reconstructed invariant-mass distributions of the ππ, ³Heπ and ³He2π systems provide hints on the role of nucleon resonances in the 3π production process.
