My area of interest lies broadly in hadron physics. I have focused
on the calculation of the electromagnetic and transition form factors,
based upon a vector-vector contact interaction. The internal structure
of the nucleon is a defining problem for nuclear physics.The most basic
observables which reflect the composite nature of the nucleon are its
electromagnetic form factors. Further, the elastic and transition form
factors can be described and related to the other observables through
the use of generalized parton distributions. Therefore, this topic
connects strongly to other thrusts of the 12 GeV upgrade program, it
will afford access to the dynamics of the non-perturbative strong
interaction responsible for resonance formation, and will be crucial in
understanding the nature of confinement and dynamical chiral symmetry
breaking in baryons, and how excited nucleons emerge from QCD.
The CLAS12 detector at Jefferson Lab is a unique instrument, which has
provided data on meson photo- and electroproduction in the resonance
excitation region. A basic motivation for this work is the need to
document a comparison between theoretical and experimental results.
