${{\mathit \chi}_{{{c0}}}{(3860)}}$

$I^G(J^{PC})$ = $0^+(0^{+ +})$ 
The assignment $\mathit J{}^{P} = 0+$ is preferred over ${}^{}2{}^{+}$ by 2.5 sigma. Observed by CHILIKIN 2017 using full amplitude analysis of the process ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit D}}{{\overline{\mathit D}}}$, where ${{\mathit D}}$ = ${{\mathit D}^{0}}$, ${{\mathit D}^{+}}$. Not seen by AAIJ 2020AI in the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}^{+}}{{\mathit D}^{-}}{{\mathit K}^{+}}$.
