transport coefficients obtained from the EMP can differ substantially from those computed from the EPP, the latter providing better agreement with the results obtained from kinetic theory (see for instance [@epvm; @tanos; @anile; @tanos2; @tanos3; @muscato; @christen2; @app]).

In relation to our developments, we note in particular Ref. [@florMHD] in which the so-called “anisotropic hydrodynamics” (that was developed in [@aniso; @mauricio]) is coupled to color fields in a way reminiscent of magnetohydrodynamics. In [@flor], an effective model for the dynamics of color fields coupled to particles is obtained from the Boltzmann-Vlasov equations by the method of moments and then applied to study chromoelectric oscillations in a dynamically evolving anisotropic background; see also [@strick]. As it will become clear in what follows, our approach resembles those adopted in these studies in that they are effective theories capable of dealing with large deviations from equilibrium.

The colorless version of the effective theory developed in this paper was investigated in [@dev] (although there it was obtained in a different way as the one followed here). It was then applied to study the evolution of matter created in heavy ion collisions at RHIC and to the calculation of hadronic observables in [@app], and compared
