Anisotropic chromodynamics and the QCD ground state
Anisotropic chromodynamics (ACD), a color gauge theory on a postulated anisotropic space-time proposed long ago, is seen to emerge as the effective theory of quarks and gluons on what most likely is the QCD ground state, the chromo magnetic liquid (CML). A description of both the kinematics and dynamics of ACD is presented, and a possible strategy for a systematic calculation of hadronic physics is outlined.

- Contrary to a widely held opinion, this research program has never questioned the validity of the basic QCD Lagrangian. It only departed from the generally accepted picture of QCD, which pretends that confinement does not play any role at short distances.Google Scholar

- It should be stressed that in its original formulation ACD didnot include dynamical (transverse) gluons. The existence of these unexpected dynamical degrees of freedom is a new important consequence of the magnetic condensation phenomenon that leads to the CML.Google Scholar
