Landau gauge condensates from global color model

Abstract

We compute the dimension-2 gluon pair condensate $g^2<AA>$ and the dimension-4 mixed quark-gluon condensate $<\bar{q}gA\cdot \gamma q>$ in Landau gauge within the framework of global color model. The result for the dynamical gluon mass is within the range given by other independent determinations. The obtained mixed Landau gauge condensate $<\bar{q}gA\cdot \gamma q>$ is clearly dependent on the definitions of the condensates. We show that the consistent result may be obtained when the same definitions are used.
