The WASA-at-COSY experiment is a near 4π detector, located at the Forschungszentrum Jülich (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 η meson in the proton-deuteron fusion reaction p d → 3He η, as well as a search for beyond standard model physics in the C-parity violating decay η → π0 e+ e−. The status of both these analyses and preliminary results are presented.
