1  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 5.0 $\sigma $.
2  From a partial wave analysis of the ${{\mathit K}^{-}}{{\mathit \omega}}$ system.
3  From a partial wave analysis of the ${{\mathit K}^{-}}$2 ${{\mathit \pi}}$ system.
4  Produced in conjunction with excited deuteron.
5  Systematic errors added correspond to spread of different fits.
