- W1539602435 abstract "Recently CLEO has studied the radiative decay of $ensuremath{Upsilon}$ into ${ensuremath{eta}}^{ensuremath{'}}$ and an upper limit for the decay has been determined. Confronted with this upper limit, most theoretical predictions for the decay fail. After briefly reviewing these predictions we reexamine the decay by separating the nonperturbative effect related to the quarkonium and that related to ${ensuremath{eta}}^{ensuremath{'}}$ or ensuremath{eta}, in which the latter is parametrized by distribution amplitudes of gluons in ${ensuremath{eta}}^{ensuremath{'}}.$ With this factorization approach we obtain theoretical predictions which are in agreement with experiment. Uncertainties in our predictions are discussed. The largest possible uncertainties are from the relativistic corrections for $J/ensuremath{psi}$ and the value of the charm quark mass. We argue that the effect of these uncertainties can be reduced by using quarkonium masses instead of using quark masses. An example of the reduction is shown with an attempt to explain the violation of the famous $14%$ rule in radiative decays of charmonia." @default.
