# ${{\boldsymbol Z}_{{c}}{(4200)}}$ $I^G(J^{PC})$ = $1^+(1^{+ -})$

was ${{\mathit X}{(4200)}^{\pm}}$
This state shows properties different from a conventional ${{\mathit q}}{{\overline{\mathit q}}}$ state. A candidate for an exotic structure. See the review on non- ${{\mathit q}}{{\overline{\mathit q}}}$ states. Reported by CHILIKIN 2014 in ${{\mathit J / \psi}}{{\mathit \pi}^{+}}$ at a significance of 6.2$\sigma$. Assignments of $0{}^{-}{}^{}$, $1{}^{-}{}^{}$, $2{}^{-}{}^{}$, and $2{}^{+}{}^{}$ excluded at 6.1$\sigma$, 7.4$\sigma$, 4.4$\sigma$, and 7.0$\sigma$ level, respectively. Needs confirmation.
