Triangle singularity in the $J / ψ \to ϕ π^{+} a_{0}^{-} (π^{-} η), ϕ π^{-} a_{0}^{+} (π^{+} η)$ decays

C. W. Xiao, J. M. Dias, L. R. Dai +2

We study the $J / ψ \to ϕ π^{+} a_{0} (980)^{-} (a_{0}^{-} \to π^{-} η)$ decay, evaluating the double mass distribution in terms of the $π^{-} η$ and $π^{+} a_{0}^{-}$ invariant masses. We show that the $π…

Disclosing $D^{} D ˉ^{}$ molecular states in the $B_{c}^{-} \to π^{-} J / ψ ω$ decay

L. R. Dai, J. M. Dias, E. Oset

We study the $B_{c}^{-} \to π^{-} J / ψ ω$ and $B_{c}^{-} \to π^{-} D^{*} D ˉ^{*}$ reactions and show that they are related by the presence of two resonances, the $X (3940)$ and $X (3930)$ , that ar…
