Sorella R. Thibes H. Verschelde Física, Astronomía y Matemáticas Yang Gribov Faddeev Propagators Condensates We report on some recent analytical results on the behaviour of the gluon and ghost propagators in EuclideanSU(2) Yang-Mills theory quantized in the maximal Abelian gauge (MAG). This gauge is of particular interestfor 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 originatingin a dimension two gluon condensate. The diagonal component of the gluon propagator displays the typicalGribov-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-diagonalghost propagator exhibits an infrared enhancement due to the Gribov restriction, while the diagonal one remainsunaffected. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437419 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37 |
