AbstractWe review some recent progress in our understanding of the lowest-lying spin-1/2 and spin-3/2 baryon magnetic moments (MMs) in terms of Chiral Perturbation Theory (ChPT) In particular, we show that at next-to-leading-order ChPT can describe the MMs of the octet baryons quite well We also make predictions for the decuplet MMs at the same chiral order Among them, the MMs of the Delta(++) and Delta(+) ate found to agree well with data within the experimental uncertainties.
