摘要：

The WASA-at-COSY experiment is a near 4 pi detector, located at the Forschungszentrum Julich (Germany). It is highly suited to study both the production of light mesons in hadron collisions and their subsequent decays. Current investigations include a study on the energy dependence of the production cross section and angular distributions of the eta meson in the proton-deuteron fusion reaction p d -> He-3 eta, as well as a search for beyond standard model physics in the C-parity violating decay eta -> pi(0) e(+) e(-). The status of both these analyses and preliminary results are presented.
