Abstract
The possibilities to determine the flavor structure of the polarized
sea (antiquark) distributions of the nucleon via vector boson
production at high energy polarized
hadron-hadron colliders, such as the Relativistic Heavy-Ion Collider
(RHIC), are studied in detail. In particular the perturbative stability
of the expected asymmetries in two representative models for the
(un)broken flavor structure are investigated by confronting perturbative
QCD leading order predictions of the expected asymmetries with their
next-to-leading order counterparts.
