Abstract

We consider the energy and the polar angle distributions of J/ψ's produced via the color-singlet and the color-octet (3S(8)1) mechanisms in Z0 → J/ψ + X at LEP. Since both distributions of the J/ψ 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 → J/ψ (or Y) + X in brief.
