Electromagnetic properties of doubly charmed baryons in Lattice QCD

Understand

We compute the electromagnetic properties of \Xi_cc baryons in 2+1 flavor Lattice QCD.

• By measuring the electric charge and magnetic form factors of \Xi_cc baryons, we extract the magnetic moments, charge and magnetic radii as well as the \Xi_cc \Xi_cc \rho 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 \Xi_cc to smaller values as compared to those of, e.g., the proton.
