was ${{\mathit X}{(10610)}}$
Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on non- ${{\mathit q}}{{\overline{\mathit q}}}$ states. Observed by BONDAR 2012 in ${{\mathit \Upsilon}{(5S)}}$ decays to ${{\mathit \Upsilon}{(nS)}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ (n = 1, 2, 3) and ${{\mathit h}_{{b}}{(mP)}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ (m = 1, 2). $\mathit J{}^{P} = 1{}^{+}$ is favored from angular analyses.
