Description

The world’s largest sample of J/ψ events accumulated at the BESIII detector offers a unique opportunity to investigate η and η′ physics via two body J/ψ radiative or hadronic decays. In recent years the BESIII experiment has made significant progresses in η/η′ decays. A selection of recent highlights in light meson spectroscopy at BESIII are reviewed in this report, including the observation of η′ → π+π−μ+μ−, observation of the cusp effect in η′ →π0π0η, search for CP-violation in η′ → π+π−e+e−, as well as the precision measurement of the branching fraction of η decays.
