${{\mathit \Xi}^{-}}$ MASS

INSPIRE   PDGID:

S022M

The fit uses the ${{\mathit \Xi}^{-}}$, ${{\overline{\mathit \Xi}}^{+}}$, and ${{\mathit \Xi}^{0}}$ masses and the ${{\mathit \Xi}}−{{\overline{\mathit \Xi}}^{+}}$ mass difference. It assumes that the ${{\mathit \Xi}^{-}}$ and ${{\overline{\mathit \Xi}}^{+}}$ masses are the same.
