Magnetic Moment of the ${\Omega }^{-}$ in QCD sumrule (QCDSR)

Abstract

The ${\Omega }^{-}$ magnetic moment was measured very accurately and experimentalists remarked that it differs from the theoretical estimates, thus posing a challenge to the latter. One such estimation uses QCDSR. We revisit this sumrule method, using condensate parameters which were obtained from fitting the differences (${\mu }_p-{\mu }_n$), (${\mu }_{{\Sigma }^{+}}-{\mu }_{{\Sigma }^{-}}$) and (${\mu }_{{\Xi }^0}-{\mu }_{{\Xi }^{-}}$) and confirm the experimental number. The ${\mu }_{{\Delta }^{++}}$ is also found to agree with the experimental estimate.
