INVESTIGATION OF THE CHARGE SYMMETRY CONSERVING REACTION dd -> (3)He n pi(0) WITH WASA-at-COSY

• One of the key experiments of the physics program of WASA-at-COSY is the determination of the p- wave contributions to the Charge Symmetry breaking amplitude in the reaction dd -> (4)He pi(0) at 1.2 GeV/c beam momentum. As a first step towards realisation of this goal the Charge Symmetry conserving reaction dd -> (3)Hen pi(0) was measured. For an overall theoretical analysis of CSB reactions in terms of Chiral Perturbation Theory this reaction channel will be used to gain information on the deuteron-deuteron initial state interaction for s- and p- wave pion production.
