Axigluonic decay of quarkonium in the chiral color model

The chiral color model predicts the existence of axigluons, i.e. a color octet of massive axial-vector gauge bosons. In this connection, of interest in the decay of quarkonium into a gluon and a virtual axigluon, the latter disintegrating into a quark-antiquark pair. In this study, an expression has been found for the decay width of quarkonium S states. Calculations have been carried out for charmonium $J/\Psi$ and bottomonium $\Upsilon$ for different values of the axigluon mass.
