${{\boldsymbol \chi}_{{c1}}{(4140)}}$ $I^G(J^{PC})$ = $0^+(1^{+ +})$ 

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. Seen by AALTONEN 2009AH, ABAZOV 2014A, CHATRCHYAN 2014M, AAIJ 2017C in ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit \chi}_{{c1}}}{{\mathit K}^{+}}$ , ${{\mathit \chi}_{{c1}}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ , and by ABAZOV 2015M separately in both prompt (4.7 ${{\mathit \sigma}}$) and non-prompt (5.6 ${{\mathit \sigma}}$) production in ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{+}$ anything. Not seen by SHEN 2010 in ${{\mathit \gamma}}$ ${{\mathit \gamma}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}$ and ABLIKIM 2015 in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit J / \psi}}{{\mathit \phi}}$ at $\sqrt {s }$ = 4.23, 4.26, 4.36 GeV.
