Abstract

Using about 226×106226\times 10^6 \jpsi\jpsi events and 106×106106\times 10^6 ψ\psi^{\prime} events collected with the BESIII detector at the BEPCII e+ee^+e^- collider, the Dalitz plot of \etapηπ+π\etap \to \eta \pi^+ \pi^- decay is studied, the direct measurement of a00(980)f0(980)a^{0}_{0}(980)-f_{0}(980) mixing is performed, X(2120)X(2120) and X(2370)X(2370) are observed in the π+πη\pi^+\pi^-\eta^\prime invariant mass spectrum, ψγπ0\psi^{\prime}\to\gamma\pi^0 and ψγη\psi^{\prime}\to\gamma\eta are observed for the first time, and the decays χcJγV\chi_{cJ}\to\gamma V (V=ϕV=\phi, ρ0\rho^0, ω\omega) are studied.
