Abstract

The $Σ^{+}$ magnetic moment is measured to be $(2.38 \pm 0.02) μ_{N}$ with use of 44 457 polarized $Σ^{+} \to p π^{0}$ decays in a charged hyperon beam. The inclusively produced $Σ^{+}$ in this 210-GeV/c beam have a polarization of about 0.20 for production angles between 2.5 and 7.0 mrad.
