  A low energy effective field theory model for QCD with a scalar color octet
field is discussed. The model relates the gluon mass, the constituent quark
masses and the quark condensate. The gluon mass comes about $\sqrt{N_c}\,
\Lambda_{QCD}$ with the quark condensate being proportional to the gluon mass
squared. The model suggests that the restoration of chiral symmetry and the
deconfinement transition occur at the same temperature and that, near the
transition, the critical exponent for the condensate is twice the gluon mass
one. The model also favors the decoupling like solution for the gluon
propagator.
