The gluon and ghost propagators in Euclidean Yang-Mills theory in the   maximal Abelian gauge: taking into account the effects of the Gribov copies   and of the dimension two condensates
  The infrared behavior of the gluon and ghost propagators is studied in SU(2) Euclidean Yang-Mills theory in the maximal Abelian gauge within the Gribov-Zwanziger framework. The nonperturbative effects associated with the Gribov copies and with the dimension two condensates are simultaneously encoded into a local and renormalizable Lagrangian. The resulting behavior turns out to be in good agreement with the lattice data.
