Abstract

Charge symmetry breaking (CSB) observables are a suitable experimental tool to examine effects induced by quark masses on the nuclear level. Previous high precision data from TRIUMF and IUCF are currently used to develop a consistent description of CSB within the framework of chiral perturbation theory. In this work the experimental studies on the reaction dd→He4π0 have been extended towards higher excess energies in order to provide information on the contribution of p-waves in the final state. For this, an exclusive measurement has been carried out at a beam momentum of p_d=1.2GeV/c using the WASA-at-COSY facility. The total cross section amounts to σ_tot=(118±18_stat±13_sys±8_ext)pb and first data on the differential cross section are consistent with s-wave pion production.
