    Future Investigations of the Flavor Dependence of Sea Quark Helicities at STAR

    Full text link
    The flavor dependence of polarized and unpolarized quark distributions in the nucleon can lead to insights into the formation of the sea. Drell-Yan measurements have pointed to flavor asymmetries in the unpolarized distributions. Collisions at sqrt{s}=500 GeV with polarized protons at RHIC will soon allow investigations of the flavor separated polarized quark distributions via W production to complement measurements from semi-inclusive DIS. We report on STAR's current plans, tracking upgrade, and expected sensitivities.Comment: 4 pages, to appear in the proceedings of the 18th International Spin Physics Symposium (Spin08), Charlottesville, Virginia, USA, October 6 - 11, 200
