Query: Local SU(3) gauge invariance in Weyl 2-spinor language and quark-gluon
  plasma equations of motion   In a new Weyl 2-spinor approach to Non abelian Gauge Theories, starting with
the local U(1) Gauge group of a previous work, we study now the SU(3) case
corresponding to quarks (antiquarks) interacting with color fields. The
principal difference with the conventional approach is that particle-field
interactions are not described by means of potentials but by the field strength
magnitudes. Some analytical expressions showing similarities with
electrodynamics are obtained. Classical equations that describe the behavior of
quarks under gluon fields might be in principle applied to the quark-gluon
plasma phase existing during the first instants of the Universe.
