${{\mathit T}_{{{c {{\overline{\mathit c}}}}}}{(4055)}^{+}}$ $I^G(J^{PC})$ = $1^+(?^{? -})$ I, G, C need confirmation.

was ${{\mathit X}{(4055)}^{\pm}}$

Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on non-${{\mathit q}}{{\overline{\mathit q}}}$ states. Needs confirmation. Seen by WANG 2015A in the ${{\mathit \psi}{(2S)}}{{\mathit \pi}^{+}}$ invariant mass distribution in ${{\mathit \psi}{(4360)}}$ $\rightarrow$ ${{\mathit \psi}{(2S)}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decay.
