Magnetic Moment of the Ω in QCD sumrule (QCDSR)

The Ω− 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 (μp − μn), (μΣ+ − μΣ−) and (μΞ0 − μΞ−) [1] and confirm the experimental number. The μ∆++ is also found to agree with the experimental estimate.
