Description

Using the world’s largest samples of J/psi and psi(3686) events produced in e+e- annihilation, BESIII is uniquely positioned to study light hadrons in radiative and hadronic charmonium decays. In particular, exotic hadron candidates including multiquark states, hybrid mesons and glueballs can be studied in high detail. Recent highlights on the light exotics searches, including the observation of an iso-scalar spin-exotic 1-+ state η1(1855) in J/ψ→γηη′, the observation of X(2600) in J/ψ→γπ+π-η′ and a PWA of Jpsiàgamma KsKspi0, will be presented.
