Özet

We compute the electromagnetic properties of Ξcc baryons in (2+1)-flavor Lattice QCD. By measuring the electric charge and magnetic form factors of Ξcc baryons, we extract the magnetic moments, charge and magnetic radii as well as the ΞccΞccρ coupling constant, which provide important information to understand the size, shape and couplings of the doubly charmed baryons. We find that the two heavy charm quarks drive the charge radii and the magnetic moment of Ξcc to smaller values as compared to those of, e.g., the proton. © 2013 Elsevier B.V.
