Effect of shadowing on initial conditions, transverse energy, and hard probes in ultrarelativistic heavy ion collisions - art. no. 044904

The effect of shadowing on the early state of ultrarelativistic heavy inn c ollisions is investigated along with transverse energy and hard process pro duction, specifically Drell-Yan, J/psi, and production. We choose several p arton distributions and parametrizations of nuclear shadowing, as well as t he spatial dependence of shadowing, to study the influence of shadowing on relevant observables. Results are presented for Au + Au collisions at root s(NN) = 200 GeV and Pbf Ph collisions at root s(NN) = 5.5 TeV.
