Description
The WASA-at-COSY experiment is a international project for light meson decay studies and dedicated production experiments. In this seminar we focus on the results on searches for pseudoscalar mesons rare decays and for a signature of a hypothetical light "dark" boson intermediating the annihilation of a dark matter particles. We present the recent results for the leptonic decays of light mesons. A special attention will be devoted to a search for the very rare eta meson decay into e+e- pair.
