QCD corrections to ${\mathbf{e}}^{+}{\mathbf{e}}^{-}\to \mathbf{J}/\mathbf{\psi gg}$ at B Factories

Abstract

In heavy quarkonium production, the measured ratio $R_{c\bar{c}}=\sigma [J/\psi +c\bar{c}+X]/\sigma [J/\psi +X]$ at B factories is much larger than existing theoretical predictions. To clarify this discrepancy, in nonrelativistic QCD (NRQCD) we find the next-to-leading-order (NLO) QCD correction to $e^{+}{e}^{-}\to J/\psi +gg$ can enhance the cross section by about 20%. Together with the calculated NLO result for $e^{+}{e}^{-}\to J/\psi +c\bar{c}$, we show that the NLO corrections can significantly improve the fit to the ratio $R_{c\bar{c}}$. The effects of leading logarithm resummation near the end point on the $J/\psi$ momentum distribution and total cross section are also considered. Comparison of the calculated cross section for $e^{+}{e}^{-}\to J/\psi +gg$ with observed cross section for $e^{+}{e}^{-}\to J/\psi +non(c\bar{c})$ is expected to provide unique information on the issue of color-octet contributions.
