Speaker

Description

BESIII has the world’s largest samples of J/ψ and ψ(3686) events from 𝑒+𝑒—annihilations, which offer an ideal and clean laboratory to study light meson spectroscopy , in particular for the search for QCD exotics. Recent important achievements in this field, including the observation of a 1-+ state, eta1(1855) in J/psi->gamma eta eta’, the observation of the X(2600) in J/psi->gamma eta’ pi+pi-, and the PWA of J/psi->gamma eta’ eta’ will be highlighted.
