The Zcs(3985) as a threshold effect from the D¯s⁎D+D¯sD⁎ interaction
We study the e+e−→K+(Ds⁎−D0+Ds−D⁎0) reaction recently measured at BESIII, from where a new Zcs state has been reported. We study the interaction of D¯sD⁎ with the coupled channels J/ψK−, K⁎−ηc, Ds−D⁎0, Ds⁎−D0 by means of an extension to the charm sector of the local hidden gauge approach. We find th...
