Light meson decays at BESIII


  • Rongsheng SHI

Primary authors


The world’s largest sample of J/ψ 1.3 billion events accumulated at the BESIII dector offers a unique opportunity to study light meson decays. In recent years the BESIII experiment has made significant progresses in eta/eta' decays, including observation of eta'->pi+pi- mu+mu-, search for the rare decays of eta’ to 4pi0 and eta’ to gamma gamma eta as well as the search for CP violation in eta’ to pi+pi- e+e-.
