Quark-quark correlations and baryon electroweak observables
arXiv:hep-ph/0204272 · doi:10.1103/PhysRevD.66.057501
Abstract
The simple independent quark models have difficulties explaining simultaneously the totality of the known hyperon magnetic moments and hyperon semi-leptonic decay rates. We show that both the Goldstone boson loop contributions and the two-quark effective exchange currents are essential in explaining these observables.
