Zcs(3985) and relevant BESIII Zc studies


  • Mr. Ziyi WANG

Primary authors


Recently, BESIII reported observation of the structure at the kinematical threshold in the $D_{s}^{-}D^{*0}+D_{s}^{*-}D^{0}$ mass distribution, which is interpreted as a tetraquark candidate, called $Z_{cs}(3985)^{-}$. This is the first candidate for a tetraquark meson containing hidden-charm with non-zero strangeness. BESIII has been devoting on the studies on the nonstrange charmoniumlike Zc states for years and produced many interesting results. In this talk, I will present the discovery of the $Z_{cs}(3985)^{-}$ and the progress of studies on the $Z_{c}$ states.
