Light Meson Decays at BESIII

Abstract

At the precision frontier of particle physics, light mesons decays play important roles in understanding strong interactions, quark Model, CP violations, and so on. They provide valuable laboratories for the testing Chiral Perturbative Theory predictions, studying the EM form factors and fundamen tal sysmmetries, and last but not least, probing new physics beyond the Standard Model. In this talk, we present the new results from BESIII about the η′ and η decays based on large J/ψ datasets.
