Abstract

It has been recently suggested that the charged charmoniumlike resonances Z_c(4100) and Z_c(4200) are two states of hadrocharmonium, related by the charm quark spin symmetry in the same way as the lowest charmonium states η_c and J/ψ. It is pointed out here that in this picture one might expect existence of their somewhat heavier strange counterparts, Z_cs, decaying to η_cK and J/ψK. Some expected properties of such charmoniumlike strange resonances are discussed that set benchmarks for their search in the decays of the strange B_s mesons.
