Description
We have measured the production polarization of 265- and 310-GeV/c Σ- in the inclusive reaction p+Cu→Σ-+X using 400-GeV/c protons. The polarization was analyzed via the asymmetry in the weak decay Σ-→n+π-, and has typical values of +0.20 with respect to the direction of the cross product of the incident-proton and Σ- momenta. Using the spin-precession technique, we have determined the Σ- magnetic moment to be -1.23 +- 0.03 +- 0.03 nuclear magnetons, where the statistical and systematic errors are shown separately
