Magnetic dipole moments of the spin-$\frac{3}{2}$ doubly heavy baryons

Abstract

The magnetic dipole moments of the spin-$\frac{3}{2}$ doubly charmed, bottom and charmed-bottom baryons are obtained by means of the light-cone QCD sum rule. The magnetic dipole moments of these baryons encode essential knowledge of their inner structure and shape deformations. The numerical results are given as, $\mu_{\Xi_{cc}^{*++}} = 2.94 \pm 0.95$, $\mu_{\Xi_{cc}^{*+}} = - 0.67 \pm 0.11$, $\mu_{\Omega_{cc}^{*+}} =- 0.52 \pm 0.07$, $\mu_{\Xi_{bb}^{*0}} = 2.30 \pm 0.55$, $\mu_{\Xi_{bb}^{*-}} = -1.39 \pm 0.32$, $\mu_{\Omega_{bb}^{*-}} = -1.56 \pm 0.33$, $\mu_{\Xi_{bc}^{*+}} = 2.63 \pm 0.82$, $\mu_{\Xi_{bc}^{*0}} = - 0.96 \pm 0.32$ and $\mu_{\Omega_{bc}^{*+}} =- 1.11 \pm 0.33$, respectively.
