QCD Axial Anomaly Enhances the ηη' Decay of the Hybrid Candidate η1(1855)
We study the hybrid mesons with the exotic quantum number IG JPC = 0+1−+ and investigate their decays into the ηη', a1(1260)π, f1(1285)η, f1(1420)η, K*(892)K-, K1(1270)K-, and K1(1400)K-,, channels. It is found that the QCD axial anomaly enhances the decay width of the ηη' channel although...
