| 520 | _ | _ | |a Investigations of charge symmetry breaking is one of the key topics for the WASA-at-COSY experiment. The study concentrates on the charge symmetry forbidden $dd \rightarrow\,^{4}\mathrm{He}\pi^{0}$ reaction. The aim is to compare the experimental results with Chiral Perturbation Theory predictions, probing hadronic effects of the up and down quarks mass difference. It was found that previous data taken close to the reaction threshold were consistent with $s$-wave. In order to probe also $p$-wave contributions, new data at sufficiently high energy were required. The measurement should comprise the charge symmetry forbidden $dd \rightarrow\,^{4}\mathrm{He}\pi^{0}$ reaction and the charge symmetry conserving reaction $dd \rightarrow\,^{3}\mathrm{He}n\pi^{0}$ to provide additionally the experimental input for the description of the initial state interactions. Results on the $dd \rightarrow\,^{3}\mathrm{He}n\pi^{0}$ and $dd \rightarrow\,^{4}\mathrm{He}\pi^{0}$ reactions with the WASA detector setup at a beam momentumof 1.2 GeV/$c$ will be presented. In addition, the status of the recent high statistics run in spring 2014 will be discussed. |
