${{\boldsymbol Z}_{{c}}{(4430)}}$ $I^G(J^{PC})$ = $1^+(1^{+ -})$ G, C need confirmation.


was ${{\mathit X}{(4430)}^{\pm}}$
Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on non- ${{\mathit q}}{{\overline{\mathit q}}}$ states. First seen by CHOI 2008 in ${{\mathit B}}$ $\rightarrow$ ${{\mathit K}}{{\mathit \pi}^{+}}{{\mathit \psi}{(2S)}}$ decays, confirmed by AAIJ 2014AG, and confirmed in a model-independent way by AAIJ 2015BH. Also seen by CHILIKIN 2014 in ${{\mathit B}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \pi}}{{\mathit J / \psi}}$ decays. $\mathit J{}^{P}$ was determined by CHILIKIN 2013 and AAIJ 2014AG.
