Abstract
Investigations of the mass and decays of the JPC=1-+ hybrid are reviewed, including calculation of the π1(1-+)→ηπ, η′π decay widths within the QCD sum rules technique. In this calculation, the recently-proposed η, η′ quark mixing scheme is employed. The results indicate that the decay width Γπ1→ηπ≈250 MeV is large compared with the decay width Γπ1→η′π≈20 MeV. Inspired by these results, some phenomenological approaches are suggested to gain an understanding of the underlying mechanism of ηπ and η′π hybrid decays.
