Precision measurement of the {Omega}{sup {minus}} magnetic moment

Using a sample of 2.35{times}10{sup 5} polarized {Omega}{sup {minus}}{r_arrow}{Lambda}{ital K}{sup {minus}} decays, we have measured the {Omega}{sup {minus}} magnetic moment to be {mu}{sub {Omega}{sup {minus}}}=({minus}2.024{plus_minus}0.056){mu}{sub {ital N}}.
