Visible and Invisible Pseudoscalar Meson Decays from Anomaly Sum Rules
Xurong Chen, Sergey Khlebtsov, Armen Oganesian +1
The decays of pseudoscalar mesons to real and virtual photons as well as neutrino-antineutrino pairs are considered in the framework of the dispersive method based on Anomaly Sum R…
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…
Search for short strings in~-annihilation
Marina Kozhevnikova, Armen Oganesian, Oleg Teryaev
In this work the behavior of power corrections to Adler finction in operator product expansion (OPE) is studied, in particular the possible contribution of operator of dimension 2.…
Analysis of the process using anomaly sum rules approach
S. Khlebtsov, A. Oganesian, O. Teryaev
The process was considered using time-like pion transition form factor, obtained in the approach of the Anomaly Sum Rules(ASR). The t…
Matching lightcone- and anomaly-sum-rule predictions for the pion-photon transition form factor
A. G. Oganesian, A. V. Pimikov, N. G. Stefanis +1
The pion-photon transition form factor is studied by employing two types of Sum Rules: Light Cone Sum Rules (LCSR) and Anomaly Sum Rules (ASR). By comparing the predictions for the…
