“…In this proceedings we report on our latest calculation of elastic electromagnetic form factors of charmed hadrons. This work extends our previous form factor calculation of spin-1/2 charmed baryons [1] to the spin-3/2 baryons composed of strange and charm quarks. Our aim is to broaden the perspective on heavy baryons by including the elastic electromagnetic form factors of the J = 3 2 + strange-charmed baryons and examining the spin-dependence of the quark dynamics.…”

The electromagnetic form factors of the spin-3/2 Ω baryons, namely the Ω, Ω * c , Ω * cc and Ω ccc , are calculated in full QCD on 32 3 x 64 PACS-CS lattices with a pion mass of 156(9) MeV. The electric charge radii and magnetic moments from the E0 and M1 multipole form factors are extracted. Results for the electric quadrupole form factor, E2, are also provided. Quark sector contributions are computed individually for each observable and then combined to obtain the baryon properties. Charm quark contributions are observed to be systematically smaller compared to the strange quark contributions in case of the charge radii and magnetic moments. E2 moments of the Ω * cc and Ω ccc are estimated significantly enough to show that their electric charge distributions are deformed. Properties of the spin-1/2 counterparts of the Ω * c and Ω * cc baryons are also computed and a comparison is presented.

The chiral corrections to the magnetic moments of the spin-1 2 doubly charmed baryons are systematically investigated up to next-to-next-to-leading order with heavy baryon chiral perturbation theory (HBChPT). The numerical results are calculated up to next-to-leading order:= 0.78µN . We also calculate the magnetic moments of the other doubly heavy baryons, including the doubly bottomed baryons (bbq) and the doubly heavy baryons containing a light quark, a charm quark and a bottom quark ({bc}q and [bc]q):

In this presentation, we summarize selectively recent results of the electromagnetic form factors of singly heavy baryons with spin 1/2 and related quantities, which were derived within a framework of the self-consistent chiral quark-soliton model. The results are compared with those from the lattice QCD and their physical implications are discussed.Keywords: the chiral quark-soliton model, pion mean fields, singly heavy baryons, electromagnetic form factors *
