Probing the proton and its excitations in full QCD

Abstract

We present a first look at the application of variational techniques for the extraction of the electromagnetic properties of an excited nucleon system. In particular, we include preliminary results for charge radii and magnetic moments of the proton, its first even-parity excitation and the ${\Delta }^{+}$.
