The paper
Abstract
We determine the η−η′ mixing angle via a procedure relatively independent of theoretical assumptions by simultaneously fitting η−eta′ reactions involving the anomaly–η,η′ → γγ,π+π−γ. We extract reasonably precise renormalized values of the octet and singlet pseudoscalar decay constants F8,F0 as well as the mixing angle θ.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

In fact, when $η$ meson is substituted by $η^'$ meson, the coupling constant $g__K_0^∗±$ is improved to $g__K_0^∗± = 20.54 GeV$, but coupling constant $g_K^∗K η^'$ is suppressed to $g_K^∗K η^' = 1.095$ when the mixing angle $θ_P = -9.95^∘$ [ref] and $f_8 = 1.26 f_π$ [ref] are applied.
