Phys. Rev. Lett. 71, 3417–3420 (1993)Measurement of the magnetic moments of the Σ+ and Σ¯- hyperonsReceived 23 August 1993; published in the issue dated 22 November 1993 We have measured the magnetic moments of the Σ+ and Σ¯ - hyperons produced by 800-GeV protons incident on a Cu target. We determine the Σ+ magnetic moment to be (2.4613±0.0034±0.0040)μN where the uncertainties are statistical and systematic, respectively. In this first measurement we determine the magnetic moment of the Σ¯ - to be -(2.428±0.036±0.007)μN. The magnetic moments of the Σ+ and Σ¯ - are consistent with each other in magnitude but opposite in sign as required by CPT invariance. © 1993 The American Physical Society URL:
