An Analysis of the Inclusive Decay $\Upsilon (1S) \to \eta^\prime X$ and Constraints on the $\eta^\prime$-Meson Distribution Amplitudes

We calculate the $\eta^\prime$-meson energy spectrum in the decay $\Upsilon (1S) \to \eta^\prime g g g \to \eta^\prime X$ in the leading-order perturbative QCD in the static quark limit for the Orthoquarkonium. Our principal result is the extraction of parameters of the $\eta^\prime g^* g$ effective...
