Full text linkIn this work, we investigate the chiral corrections to the magnetic moments
of the spin-23​ 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∗++​​=1.72μN​, μΞcc∗+​​=−0.09μN​,
μΩcc∗+​​=0.99μN​. As a by-product, we have also calculated
the magnetic moments of the spin-23​ doubly bottom baryons and charmed
bottom baryons:
μΞbb∗0​​=0.63μN​, μΞbb∗−​​=−0.79μN​,
μΩbb∗−​​=0.12μN​, μΞbc∗+​​=1.12μN​,
μΞbc∗0​​=−0.40μN​, μΩbc∗0​​=0.56μN​.Comment: 10 pages,2 figures. arXiv admin note: text overlap with

Full text linkWe have systematically investigated the spin-23​ to
spin-21​ doubly charmed baryon transition magnetic moments to the
next-to-next-to-leading order in the heavy baryon chiral perturbation theory
(HBChPT). Numerical results of transition magnetic moments and decay widths are
presented to the next-to-leading order:
μΞcc∗++​→Ξcc++​​=−2.35μN​,
μΞcc∗+​→Ξcc+​​=1.55μN​,
μΩcc∗+​→Ωcc+​​=1.54μN​,
ΓΞcc∗++​→Ξcc++​​=22.0 keV,
ΓΞcc∗+​→Ξcc+​​=9.57 keV,
ΓΩcc∗+​→Ωcc+​​=9.45 keV.Comment: arXiv admin note: text overlap with arXiv:1707.02765,
