Magnetic moments of the spin- 32 doubly heavy baryons

Abstract

In this work, we investigate the chiral corrections to the magnetic moments of the spin-32 doubly charmed baryons systematically up to next-to-next-to-leading order with the heavy baryon chiral perturbation theory. The numerical results are given up to next-to-leading order: μΞcc∗++=2.61μN, μΞcc∗+=-0.18μN, μΩcc∗+=0.17μN. As a by-product, we have also calculated the magnetic moments of the spin-32 doubly bottom baryons and charmed bottom baryons: μΞbb∗0=2.83μN, μΞbb∗-=-1.33μN, μΩbb∗-=-1.54μN, μΞbc∗+=3.22μN, μΞbc∗0=-0.84μN, μΩbc∗0=-1.09μN.
