The symbol *B* is used for branching ratios, *f* for production fractions, and σ for cross sections. The decay amplitudes for longitudinal, parallel, and perpendicular transverse polarization in pseudoscalar to vector-vector decays are denoted $A_0$, $A_\parallel$, and $A_\perp$, respectively, and the definitions $\delta_\parallel = \mbox{arg}(A_\parallel/A_0)$ and $\delta_\perp = \mbox{arg}(A_\perp/A_0)$ are used for their relative phases. The inclusion of charge conjugate modes is always implied.
