Valence-quark-core and meson-cloud effects on electromagnetic form factors of $\Delta$ baryons
Electromagnetic form factors and electromagnetic properties of $\Delta$ baryons are studied in the perturbative chiral quark model (PCQM) using quark wavefunctions predetermined from proton charge form factor data. Our predictions agree reasonably with lattice-QCD and other phenomenological results. For charged $\Delta...
