摘要：

The direct production rate of J/psi, via the color-octet mechanism is calculated at the Z resonance. The color-octet production process Z --> <J/psi q(q)over bar> is shown to have a substantial branching ratio as well as a distinctive energy spectrum, which can be used as a powerful tool to distinguish from the color-singlet direct production of the J/psi.
