The intermediate resonance ${{\mathit X}}$ is parametrized by a constant-width, relativistic Breit-Wigner. 3  T-matrix pole from coupled channel K-matrix fit to data on ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ (ABLIKIM 2015AE) and ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit K}_S^0}$ ${{\mathit K}_S^0}$ (ABLIKIM 2018AA). 4  Partial wave analysis of the data on ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\overline{\mathit \Lambda}}}{{\mathit \Lambda}}$ from BARNES 2000 .
