Recent results from BESIII

Abstract

Using about $226\times 10^6$ $\jpsi$ events and $106\times 10^6$ $ψ^{\prime}$ events collected with the BESIII detector at the BEPCII $e^+e^-$ collider, the Dalitz plot of $\etap \to ηπ^+ π^-$ decay is studied, the direct measurement of $a^{0}_{0}(980)-f_{0}(980)$ mixing is performed, $X(2120)$ and $X(2370)$ are observed in the $π^+π^-η^\prime$ invariant mass spectrum, $ψ^{\prime}\toγπ^0$ and $ψ^{\prime}\toγη$ are observed for the first time, and the decays $χ_{cJ}\toγV$ ($V=ϕ$, $ρ^0$, $ω$) are studied.
