Abstract

We have measured the magnetic moments of the SIGMA+ and SIGMABAR- hyperons produced by 800-GeV protons incident on a Cu target. We determine the SIGMA+ magnetic moment to be (2.4613 +/- 0.0034 +/- 0.0040)mu(N) where the uncertainties are statistical and systematic, respectively. In this first measurement we determine the magnetic moment of the SIGMABAR- to be -(2.428 +/- 0.036 +/- 0.007)mu(N). The magnetic moments of the SIGMA+ and SIGMABAR- are consistent with each other in magnitude but opposite in sign as required by CPT invariance.

Abstract

We have measured the asymmetry parameter (${\mathrm{\ensuremath{\alpha}}}_{\ensuremath{\gamma}}$) in the hyperon radiative decay ${\mathrm{\ensuremath{\Sigma}}}^{+}$\ensuremath{\rightarrow}p\ensuremath{\gamma} with a sample of 34 754\ifmmode\pm\else\textpm\fi{}212 events obtained in a polarized charged hyperon beam experiment at Fermilab. We find ${\mathrm{\ensuremath{\alpha}}}_{\ensuremath{\gamma}}$=-0.720\ifmmode\pm\else\textpm\fi{}0.086\ifmmode\pm\else\textpm\fi{}0.045, where the quoted errors are statistical and systematic, respectively.
