${{\overline{\mathit \Xi}}^{+}}$ MASS

INSPIRE   PDGID:

S022M1

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.
