Abstract :
We consider the energy and the polar angle distributions of Jψʹs produced via the color-singlet and the color-octet (3S1(8)) mechanisms in Z0 → Jψ + X at LEP. Since both distributions of the Jψ produced via color-octet mechanism are significantly different from those via color-singlet mechanism, these observables can be used as tests of color-octet production mechanism for heavy quarkonia. We also discuss Z0 → Y + X and W → Jψ(or Y) + X in brief.
