CDF ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$
1  From an amplitude analysis of the decay ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \phi}}{{\mathit K}^{+}}$ with a significance of 8.4 $\sigma$.
2  Statistical significance of more than 5 $\sigma$.
3  Statistical significance of more than 6 ${{\mathit \sigma}}$.
4  Statistical significance of 3.1 $\sigma$.
5  From a fit assuming an ${\mathit S}{\mathrm -wave}$ relativistic Breit-Wigner shape above a three-body phase-space non-resonant component with statistical significance of more than 5 ${{\mathit \sigma}}$.
6  Statistical significance of 3.8 $\sigma$.
