Status of η′ meson decays at BESIII

A sample of 1.31×109J/ψ events collected with the BESIII detector provides a clean source of 6.7×106η′ mesons for decay studies. Some of the highlights include first observations of Dalitz decays η′→γe+e− and η′→ωe+e− as well as the most precise up to now studies of η′→π+π−γ and η′→3π dynamics.
