$g_{ÏÏÏ}$ reexamined
arXiv:hep-ph/9608331 · doi:10.1103/PhysRevD.55.249
Abstract
The transition constant for the hadronic decay $Ï\rightarrow ÏÏ$ is investigated by means of QCD sum rules in external axial field. The obtained value for $g_{ÏÏÏ}$ is about 16 GeV${}^{-1}$ that is in a good agreement with experimental data.
