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

摘要

We have systematically investigated the magnetic moments of spin- 1 2 doubly charmed baryons in the framework of the heavy baryon chiral perturbation theory. In this paper, one loop corrections with intermediate spin- 1 2 and spin- 3 2 doubly charmed baryon states are considered. The numerical results are calculated to next-to-leading order: μ Ξ c c + + = 0.35 μ N , μ Ξ c c + = 0.62 μ N , μ Ω c c + = 0.41 μ N . Our results may be useful for future experiment and chiral extrapolation of the lattice QCD.
