We study the $B ˉ_{s}^{0} \to J / ψ f_{0} (980)$ and $B ˉ_{s}^{0} \to J / ψ a_{0} (980)$ reactions, and pay attention to the different sources of isospin violation and mixing of $f_{0} (980)$ and $…

Looking for the exotic $X_{0} (2866)$ and its $J^{P} = 1^{+}$ partner in the $B ˉ^{0} \to D^{() +} K^{-} K^{() 0}$ reactions

L. R. Dai, R. Molina, E. Oset

We propose two reactions, $B ˉ^{0} \to K^{0} D^{+} K^{-}$ and $B ˉ^{0} \to K^{* 0} D^{*+} K^{-}$ , already measured at Belle, to look into the $J^{P} = 0^{+}$ , $X_{0} (2866)$ state and a $1^{+}$ …
