Shadowing effects on vector boson production
- Author(s): Vogt, R.

We explore how nuclear modifications to the nucleon structure functions, shadowing, affect massive gauge boson production in heavy ion collisions at different impact parameters. We calculate the dependence of Z^0, W^+ and W^- production on rapidity and impact parameter to next-to-leading order in Pb+Pb collisions at 5.5 TeV/nucleon to study quark shadowing at high Q^2. We also compare our Pb+Pb results to the pp rapidity distributions at 14 TeV.
