We report on some recent analytical results on the behaviour of the gluon andghost propagators in Euclidean SU(2) Yang-Mills theory quantized in the maximalAbelian gauge (MAG). This gauge is of particular interest for the dualsuperconductivity picture to explain color confinement. Two kinds of effectsare taken into account: those arising from a treatment of Gribov copies in theMAG and those arising from a dynamical mass originating in a dimension twogluon condensate. The diagonal component of the gluon propagator displays thetypical Gribov-type behaviour, while the off-diagonal component is of theYukawa type due to the dynamical mass. These results are in qualitativeagreement with available lattice data on the gluon propagators. Theoff-diagonal ghost propagator exhibits an infrared enhancement due to theGribov restriction, while the diagonal one remains unaffected.Comment: 6 pages. Talk given by S.P. Sorella at the "I Latin American Workshop  on High Energy Phenomenology (I LAWHEP)", December 1-3 2005, Instituto de  Fisica, UFRGS, Porto Alegre, Rio Grande Do Sul, Brasi
