Spin-32 doubly charmed baryon contribution to the magnetic moments of the spin-12 doubly charmed baryons

We have systematically investigated the magnetic moments of spin-12 doubly charmed baryons in the framework of the heavy baryon chiral perturbation theory. In this paper, one loop corrections with intermediate spin-12 and spin-32 doubly charmed baryon states are considered. The numerical results are calculated to next-to-leading order: μΞcc++=0.35μN, μΞcc+=0.62μN, μΩcc+=0.41μN. Our results may be useful for future experiment and chiral extrapolation of the lattice QCD.
