Popis: In our previous coupled channel analysis based on the Cornell effective quark–quark interaction, it was indicated that the \({\psi(3S)}\) solution corresponding to \({\psi(4040)}\) originates from a \({{\rm D}^{^{*}}\overline{{\rm D}}^{*}}\) channel state. In this article, we report on a simultaneous analysis of the \({\psi}\)- and \({\Upsilon}\)-family states. The most conspicuous outcome is a finding that the \({\Upsilon(5S)}\) solution corresponding to \({\Upsilon(10860)}\) originates from a \({{\rm B}^{*}\overline{{\rm B}}^{*}}\) channel state, very much like \({\psi(3S)}\). Some other characteristics of the result, including the induced very large S–D mixing and relation of some of the solutions with newly observed heavy quarkonia-like states are discussed.
