Investigation of the Lightest Hybrid Meson Candidate with a Coupled-Channel Analysis of $\bar{p}p$-, ${\pi }^{-}p$- and $\pi \pi$-Data

B. Kopf, M. Albrecht, H. Koch +4

A sophisticated coupled-channel analysis is presented that combines different processes: the channels ${\pi }^0{\pi }^0\eta$, ${\pi }^0\eta \eta$ and $K^{+}{K}^{-}{\pi }^0$ from $\bar{p}p$ annihilations, the P- and D…
