The effect of shadowing on the early state of ultrarelativistic heavy ion collisions is investigated along with transverse energy and hard process production, specifically Drell-Yan, J/{psi}, and {upsilon} production. We choose several parton distributions and parametrizations of nuclear shadowing, as well as the spatial dependence of shadowing, to study the influence of shadowing on relevant observables. Results are presented for Au+Au collisions at {radical}(s{sub NN})=200 GeV and Pb+Pb collisions at {radical}(s{sub NN})=5.5 TeV. (c) 2000 The American Physical Society.
