Abstract

We present calculations of the spin-spin asymmetry in the low transverse momentum production of ψ's and {A figure is presented}'s in polarized proton-proton collisions. A perturbative QCD approach using quarkonium wavefunctions derived from non-relativistic potential models is employed. The contributions from gg→χ_0,2 and gg→g³S₁ are known to dominate in this approach and we exhibit the sensitivity of the polarization asymmetry to various choices of polarized gluon distribution.
