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 6.0 $\sigma $.
2  From a fit to the invariant mass spectrum with a significance of 3.1 $\sigma $.
