Non-Abelian axial anomaly, axial-vector duality, and the pseudoscalar glueball
Sergey Khlebtsov, Yaroslav Klopot, Armen Oganesian +1
We generalize the dispersive approach to axial anomaly by A.D. Dolgov and V.I. Zakharov to a non-Abelian case with arbitrary photon virtualites. We derive the anomaly sum rule for…
Dispersive approach to non-Abelian axial anomaly
Sergey Khlebtsov, Yaroslav Klopot, Armen Oganesian +1
Manifestations of strong and electromagnetic axial anomalies in two-photon decays of and mesons are studied. Applying dispersive approach to axial anomaly in the singlet c…
Axial anomaly and vector meson dominance model
Yaroslav Klopot, Armen Oganesian, Oleg Teryaev
The dispersive representation of axial anomaly leads to the anomaly sum rules (ASRs), exact nonperturbative relations in QCD. The analytical continuation of the ASRs to the time-li…
Transition form factors of , and mesons: What can be learned from anomaly sum rule?
Yaroslav Klopot, Armen Oganesian, Oleg Teryaev
We have studied the applications of the anomaly sum rule to the transition form factors of light pseudoscalar mesons: , and . This nonperturbative QCD approach can be…
Axial Anomaly and Light Cone Distributions
Yaroslav Klopot, Armen Oganesian, Oleg Teryaev
Axial anomaly leads to exact sum rules for transition form factors providing the important constraints to respective distribution amplitudes. This rigorous NPQCD approach is valid…
Transition Form Factors and Mixing of Pseudoscalar Mesons from Anomaly Sum Rule
Yaroslav Klopot, Armen Oganesian, Oleg Teryaev
Transition form factors of pi^0, eta, eta' mesons are investigated by means of the anomaly sum rule -- an exact nonperturbative relation which follows from the dispersive represent…
