Abstract

In this work, we investigate the chiral corrections to the magnetic moments of the spin-3\over 2 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: μ_Ξ^*++_cc=1.72μ_N, μ_Ξ^*+_cc=-0.09μ_N, μ_Ω^*+_cc=0.99μ_N. As a by-product, we have also calculated the magnetic moments of the spin-3\over 2 doubly bottom baryons and charmed bottom baryons: μ_Ξ^*0_bb=0.63μ_N, μ_Ξ^*-_bb=-0.79μ_N, μ_Ω^*-_bb=0.12μ_N, μ_Ξ^*+_bc=1.12μ_N, μ_Ξ^*0_bc=-0.40μ_N, μ_Ω^*0_bc=0.56μ_N.
