Abstract
We investigate the large transverse momentum Drell-Yan process, includ ing the effects of gamma-Z interference, al RHIC energies, as a method of studying polarised parton distributions. Both single- and double-s pin asymmetries are studied. It is shown that while the double-spin as ymmetries are sizeable in the region of small dilepton masses, the sin gle-spin asymmetries become significant at the Z peak. There is a high degree of sensitivity to the input parton distributions. Numerical es timates for the cross-sections at RHIC energies are also presented.
