${{\mathit T}_{{{c {{\overline{\mathit s}}} 0}}}^{*}{(2900)}}$

$I(J^P)$ = $1(0^{+})$ 
Observed by LHCb in AAIJ 2023B using a simultaneous amplitude analysis of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\overline{\mathit D}}^{0}}{{\mathit D}_{{{s}}}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit D}^{-}}{{\mathit D}_{{{s}}}^{+}}{{\mathit \pi}^{+}}$. The ${{\mathit T}_{{{c {{\overline{\mathit s}}} 0}}}^{*}{(2900)}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit T}_{{{c {{\overline{\mathit s}}} 0}}}^{*}{(2900)}^{++}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{+}}{{\mathit \pi}^{+}}$ decays are observed with 8.0 and 6.5 $\sigma $ significance, respectively.
