We explore how nuclear modifications to the nucleon structure
functions, generally referred to as shadowing,
affect massive gauge boson production in heavy ion collisions at
different impact parameters. We calculate the dependence of
Z0, 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 Q2. We also calculate homogeneous shadowing
effects in Pbp and pPb at 5.5 TeV. All our results are compared to
pp interactions at 5.5 TeV to take isospin effects into account.
