Electromagnetic properties of doubly charmed baryons in Lattice QCD
Abstract
We compute the electromagnetic properties of cc baryons in 2+1 flavor Lattice QCD. By measuring the electric charge and magnetic form factors of cc baryons, we extract the magnetic moments, charge and magnetic radii as well as the cc cc 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 cc to smaller values as compared to those of, e.g., the proton.
