Abstract
The WASA-at-COSY experiment has collected 3×107 events with η mesons produced via the reaction pd→He3η at T=1.0GeV. Using this data set, we evaluate the branching ratios of the decays η→π+π-γ, η→e+e-γ, η→π+π-e+e-, and η→e+e-e+e-. The branching ratios are normalized to the η→π+π-π0 decay. In addition an upper limit on a CP-violating asymmetry in η→π+π-e+e- is extracted.
