Properties incompatible with a ${{\mathit q}}{{\overline{\mathit q}}}$ structure (exotic state). See the review on "Heavy Non-${{\mathit q}}{{\overline{\mathit q}}}$ Mesons." Seen by AAIJ 2021E in ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit T}_{{{c {{\overline{\mathit c}}} {{\overline{\mathit s}}} 1}}}{(4220)}^{+}}{{\mathit \phi}}$ with ${{\mathit T}_{{{c {{\overline{\mathit c}}} {{\overline{\mathit s}}} 1}}}{(4220)}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit K}^{+}}$ using an amplitude analysis of ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance (accounting for systematic uncertainties) of 5.9 $\sigma $. The $\mathit J{}^{P} = 1{}^{+}$ assignment is favored over ${}^{}1{}^{-}$ with a significance of 2 $\sigma $ and other assignments are disfavored by 4.9 $\sigma $.
