Axial Anomaly and Transition Formfactors
Oleg Teryaev, Yaroslav Klopot, Armen Oganesian
We study photon-meson transition formfactors of light mesons in the kinematics, where one photon is real and other is virtual. Dispersive approach to axial anomaly leads to the ano…
Dispersive Approach to Abelian Axial Anomaly, Mixing of Pseudoscalar Mesons and Symmetries
Y. N. Klopot, A. G. Oganesian, O. V. Teryaev
We suggest a rigorous generalization of the pseudoscalar mesons mixing description in SU(3) basis. It is shown that the appearance of extra massive state nicknamed in the paper as…
Dispersive Approach to Abelian Axial Anomaly and Mixing
Y. N. Klopot, A. G. Oganesian, O. V. Teryaev
We investigate what can be learnt about the - mixing by means of dispersive representation of axial anomaly. We show that our method leads to the strong bounds for the $η-η…
