- 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.
