Description
At BESIII, the lineshapes of $e^+e^- \to \phi \eta^\prime$, $\phi \eta$, $KK$, $\omega \pi^0$, $\eta \pi\pi$, $\omega \pi\pi$ are measured from 2.0 to $3.08~\rm GeV$, where resonant structures are observed in these processes. Multiple lineshapes of intermediate state are obtained by a partial wave analysis of $e^+e^- \to K^+ K^- \pi^0 \pi^0$, $K^+K^- \pi^0$ and the structures observed provide essential input to understand the nature of $\phi(2170)$. These results provide important information for light flavor vector mesons i.e. excited $\rho$, $\omega$ and $\phi$, for energy regions above $2~\rm GeV$.
