Abstract

The electromagnetic form factors of Σc, Ξcc, Ωc and Ωcc baryons are computed and their electric and magnetic charge radii as well as their magnetic moments are extracted in 2+1 flavor Lattice QCD. Extrapolated physical point results show that the charge radii and magnetic moments are smaller compared to those of, e.g., proton. Investigating the individual quark contributions suggests that the existence of the heavy charm quark is responsible of such decrease.
