Description
Polarized heavy quarkonium productions in Z0 decays are considered. We find that polarizations of the produced quarkonia are independent of that of the parent Z0 provided that one considers the energy distribution or the total production rate. Produced J/ψ close-quote s via the color-octet and the color-singlet mechanisms are expected to be 19% and 29% longitudinally polarized, respectively. The energy dependence of η1,8(x) ≡dΓ1,8L/dx/dΓ1,8/dx is very sensitive to the production mechanism, and, therefore, the measurement of η(x)expt will be an independent probe of the color-octet mechanism. copyright 1997 The American Physical Society
