<b>Recent Advances in the Calculation of Hadron Form Factors<br>
Using Dyson-Schwinger Equations of QCD</b><br>
<br>
Elastic and transition form factors of nucleon excited states
provide vital information about their<br>
structure and composition. They are a measurable and physical
manifestation of the nature of the<br>
hadrons constituents and the dynamics that binds them together. In
this respect, two emergent <br>
phenomena of Quantum Chromodynamics (QCD), confinement and dynamical
chiral symmetry<br>
breaking, appear to play an important role; and Dyson-Schwinger
equations (DSEs) have been<br>
established as a nonperturbative quantum field theoretical approach
for the study of continuum<br>
strong QCD which is able to connect such emergent phenomena with the
behavior of form factors.
