(${\boldsymbol \mu}_{{{\boldsymbol \Xi}^{-}}}$ + ${\boldsymbol \mu}_{{{\overline{\boldsymbol \Xi}}^{+}}}$) $/$ $\vert {\boldsymbol \mu}_{{{\boldsymbol \Xi}^{-}}}\vert$ INSPIRE search

A test of $\mathit CPT$ invariance. We calculate this from the ${{\mathit \Xi}^{-}}$ and ${{\overline{\mathit \Xi}}^{+}}$ magnetic moments above.
