Description

The world’s largest sample of $J/\psi$ events accumulated at the BESIII detector offers a unique opportunity to investigate $\eta$ and $\eta'$ physics via two body $J/\psi$ radiative or hadronic decays. In recent years the BESIII experiment has made significant progresses in $\eta$/$\eta'$ decays. A selection of recent highlights in light meson decays at BESIII are reviewed in this report, including the precision measurement of Dalitz plots, transition form factor measurements, as well as the search for rare/forbidden decays of $\eta$/$\eta'$.
