Query: Infinite Nuclear Matter on the Light Front: A Modern Approach to
  Brueckner Theory   Understanding an important class of experiments requires that light-front
dynamics and related light cone variables k^+ and k_perp be used. If one uses
k^+ as a momentum variable, the corresponding canonical spatial variable is
x^-=x^0-x^3 and the time variable is x^0+x^3. This is the light front (LF)
approach of Dirac. A relativistic light front formulation of nuclear dynamics
is developed and applied to treating infinite nuclear matter in a method which
includes the corelations of pairs of nculeons. This is light front Brueckner
theory.
