Two new sum rules for octet-baryon magnetic moments (\mu) and   constraints on QCD sum rules from new experimental determination of \mu-s for   the decuplet
  Recently the \mu_{\Delta ^{++}} was found from a fit to (\pi^+)p scattering. This enable us to pinpoint condensate parameters more precisely in the context of QCD sum rules (QCDSR).   In the octet sector, the Coleman-Glashow sum rule (CGSR) is violated by the experimental \mu-s. QCDSR allows us to write down two sum rules similar to the CGSR, which are obeyed by the experimental magnetic moments, whereas they rule out a specific model using the Wilson loop approach and a particular chiral quark model.   It is amusing to note that the QCDSR allows us to write down the quark and gluon condensates in terms of measurables like the \mu-s of the nucleons and the \Sigma^{+/-}.
