Phenomenological quark model for baryon magnetic moments and beta decay ratios ( $G_{A} / G_{V}$ )

Baryon magnetic moments and beta decay ratios ( $G_{A} / G_{V}$ ) are calculated in a phenomenological quark model. Non-static effects of pion exchange and orbital excitation are included. Good agreement with experiment is found for a combined fit to all measured baryon magnetic moments and beta decay ratios. The model predicts an antiquark content for the proton that is consistent with the Gottfried sum rule.
