Testing the usage of a generalization of the Witten-Veneziano relation in a bound-state approach to $\eta$ and $\eta'$ mesons

The results of the Dyson-Schwinger approach utilizing the Witten-Veneziano relation to obtain a description of the η and η ′ mesons, are compared with the results obtained when Shore’ s generalization of theWitten-Veneziano relation is used instead. On the examples of three differentmodel interactions, we find that irrespective of the concrete model dynamics, our Dyson-Schwinger approach is phenomenologically more successful in conjunction with the standard Witten-Veneziano relation than with the generalization valid, at least in principle, in all orders in the 1/Nc expansion.
