Relativistic Quark String Models

I will give a brief introduction to work done by my students Siraj Kuthinikunhammed and Jonatan Posligua.  The theory of the strong interaction is quantum chromodynamics.  It is a local $SU(3)$ gauge theory.  The degrees of freedom are quarks and gluons.  The theory is assumed to confine quarks.  Pertrubation theory is not applicable due to the strength of the interaction.  The structure of strongly interacting systems of particles can be investigated by scattering electrons or photons off of strong charge carriers (quarks).  The energies needed to be sensitive to sub-hadronic features are relativistic.  I discuss a class of simple relativistic models of these systems based on locally gauge invariant degrees of freedom whose structure is motivated by strong-coupling Hamiltonian lattice QCD.
