Strange hadrocharmonium
It has been recently suggested that the charged charmoniumlike resonances Zc(4100) and Zc(4200) are two states of hadrocharmonium, related by the charm quark spin symmetry in the same way as the lowest charmonium states ηc and J/ψ. It is pointed out here that in this picture one might expect existen...
