Electromagnetic structure of charmed baryons

Abstract

We compute the electromagnetic form factors of charmed baryons (∑ c, (ξcc, ω c and ω cc) in 2+1 Lattice QCD and extract their electric and magnetic charge radii as well as their magnetic mo-ments. Such observables are important to understand the structure and the inner dynamics of the hadrons. We find that the existence of the heavy quarks drive the charge radii and magnetic moments to smaller values as compared to those of, e.g., proton.
