Description

BESIII has collected about 9 pb$^{-1}$ electron positron annihilation sample at 4.0–4.6 GeV. With this large sample, new searches for exotic states and precise studies of line-shape during this energy region are performed. We present the measurements of cross sections with final states $\pi^{+} \pi^{-} \psi(2S)$, $K \bar{K} J/\psi$, $\pi^{+} \pi^{-} h_{c}$, $\pi^{+} \pi^{-} J/\psi$, $\gamma \eta_{c}$, $\eta Y(2175)$, and $\pi^{0} \pi^{0} \psi(2S)$, and corresponding interpretations of observed structures are discussed.
