چکیده
We determine the η−η mixing angle via a procedure relatively independent of theoretical assumptions by simultaneously fitting η, η 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. * Research supported in part by the National Science Foundation

We report on a confined quark model calculation of the transition form factors for the radiative decays of η(η) → γl+l− and η(η) → γπ+π−. The η/η mixing angle θP is determined from the set of data on the electromagnetic η(η ) decays. It is found that θP ∼ −16.5o. The analysis of the dipionic mass distribution in the decay η → γπ+π− confirms the existence of a non-resonant contribution which is ...

We investigate what can be learnt about the η -η mixing by means of dispersive representation of axial anomaly. We show that our method leads to the strong bounds for the η − η mixing angle: θ = −15.3◦ ± 1. Moreover, our result manifests also a dramatic dependence of the width Γη→2γ on the mixing angle θ. This property explains how the relatively small mixing strongly effects the decay width.

The radiative decays η ′ (η) → γγ are discussed. The modifications of the conventional PCAC formulae due to the gluonic contribution to the flavour singlet axial anomaly are given. The decay constants satisfy a modified Dashen formula which generalises the Witten–Veneziano formula for the mass of the η ′. It is shown how the topological susceptibility in QCD with massive, dynamical quarks may b...
