  We report on some recent analytical results on the behaviour of the gluon and
ghost propagators in Euclidean SU(2) Yang-Mills theory quantized in the maximal
Abelian gauge (MAG). This gauge is of particular interest for the dual
superconductivity picture to explain color confinement. Two kinds of effects
are taken into account: those arising from a treatment of Gribov copies in the
MAG and those arising from a dynamical mass originating in a dimension two
gluon condensate. The diagonal component of the gluon propagator displays the
typical Gribov-type behaviour, while the off-diagonal component is of the
Yukawa type due to the dynamical mass. These results are in qualitative
agreement with available lattice data on the gluon propagators. The
off-diagonal ghost propagator exhibits an infrared enhancement due to the
Gribov restriction, while the diagonal one remains unaffected.
