Lowest-lying spin-1/2 and spin-3/2 baryon magnetic moments in chiral perturbation theory

  • We 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 Δ++ and Δ+ are found to agree well with data within the experimental uncertainties.

Abstract: 

We 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 Δ++ and Δ+ are found to agree well with data within the experimental uncertainties.
