BESIII (Beijing Spectrometer) is a general purpose 4π detector at the upgraded BEPCII (Beijing Electron and Positron Collider) that operated in the τ-charm threshold energy region[1]. Since 2009, it has collected the world’s largest data samples of J/ψ, ψ(3686), ψ(3770) and ψ(4040) decays. More recently, data were taken in the energy region above 4 GeV, where energies up to about 4.6 GeV are accessible. These data are being used to make a variety of interesting and unique studies of light hadron spectroscopy, charmonium spectroscopy, high-statistics measurements of charmonium decays and D meson decays.

Amplitude analyses of J/psi radiative decays, the spin-parity determination of Zc(3900), as well amplitude analyses of charm meson decays will be reported.
