OMEG - 18.5 ${{\mathit K}^{-}}$ ${{\mathit p}}$ $\rightarrow$ 3 ${{\mathit K}}{{\mathit p}}$
1  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 3.5 $\sigma $.
2  A subsequent amplitude analysis of ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ by AAIJ 2021E did not confirm this measurement.
