Deskripsi

We have systematically investigated the spin-32 to spin-12 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.
