${{\mathit T}_{{{{{\overline{\mathit c}}} {{\overline{\mathit s}}} 0}}}^{*}{(2870)}^{0}}$ $I(J^P)$ = $?(0^{+})$

was ${{\mathit X}_{{{0}}}{(2900)}}$

An exotic state with minimal quark content ${{\overline{\mathit c}}}{{\mathit d}}{{\overline{\mathit s}}}{{\mathit u}}$. Observed by AAIJ 2020AI using full amplitude analysis of ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}^{+}}{{\mathit D}^{-}}{{\mathit K}^{+}}$ decays.
