RVUE ${{\overline{\mathit p}}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}{{\mathit \eta}}$
1  From T-matrix pole based on combined fit of Crystal Barrel and ${{\mathit \pi}}{{\mathit \pi}}$ scattering data (ALBRECHT 2020), and COMPASS data (ADOLPH 2015), using a coupled-channel model of ${{\mathit \eta}}{{\mathit \pi}}$, ${{\mathit \eta}^{\,'}}{{\mathit \pi}}$ and ${{\mathit K}}{{\overline{\mathit K}}}$ systems.
2  The coupled-channel analysis of both the ${{\mathit \eta}}{{\mathit \pi}}$ and ${{\mathit \eta}^{\,'}}{{\mathit \pi}}$ systems using ADOLPH 2015 data.
3  Superseded by KOPF 2021.
