【 摘 要 】

Electromagnetic form factors of D and D∗ mesons and Ξcc, Σc, Ωcand Ωccbaryons are calculated in 2+1 flavor lattice QCD. As a by product of this calculation electric/magnetic charge radii and magnetic moments are extracted. Compared to the PDG values of the light- sector, i.e. pion and proton, charmed hadron results are systematically smaller.
