Recent results on charmonium-like (exotic) XYZ states at the BESIII/BEPCII experiment in Beijing/China

Abstract

With about 12 fb${}^{-1}$ collected XYZ data sets, BESIII continues the exploration of the exotic charmonium-like states. In this talk, recent results on the measurements of the spin-parity determination of $Z_{\mathrm{c}}(3900)$, as well as on line-shapes of $e^{+}{e}^{-}\to J/\psi \pi \pi ,h_{\mathrm{c}}\pi \pi ,\psi (2S){\pi }^0{\pi }^0/{\pi }^{+}{\pi }^{-}$, and ${\pi }^{+}{D}^0{D}^{\ast -}$ from open charm are discussed. Also, the recent observation of $e^{+}{e}^{-}\to \varphi {\chi }_{c1/2}$ at $\sqrt{(}s)=4.6$ GeV is reported.
