was ${{\mathit X}{(4100)}^{\pm}}$
Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on non-${{\mathit q}}{{\overline{\mathit q}}}$ states. Reported by AAIJ 2018AN in the ${{\mathit \eta}_{{{c}}}{(1S)}}{{\mathit \pi}^{+}}$ invariant mass distribution in ${{\overline{\mathit B}}^{0}}$ $\rightarrow$ ${{\mathit \eta}_{{{c}}}{(1S)}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays with a significance of 3.4$\sigma $. $\mathit J{}^{P} = 0{}^{+}$ or ${}^{}1{}^{-}$ assignment consistent with data.
