Preliminary results from E756 on the Ξ- and Ω- magnetic moments

We have used the spin precession technique to measure the Ξ- and Ω- magnetic moments. The preliminary results are μ(Ξ-)=-0.64±0.02 nuclear magnetons and μ(Ω-)=-2.0±0.2 nuclear magnetons where the error for both measurements is statistical. The polarization of Ξ-'s produced at 2.5 mr by 800 GeV protons on a Be target was 11% while the polarization of Ω-'s was consistent with zero. Polarized Ξ-'s and Ω-'s were produced using spin transfer from a polarized neutral hyperon beam. The Ω- polarization at 325 GeV/c was 6.5%
