All rights reserved. We thank E Breitenlohner, J.W. van Holten, E De Jonghe and D. Maison for discussionsWe prove that three-dimensional N=1 supersymmetric Yang Mills-Chem-Simons theory is finite to all loop orders, In general this leaves open the possibility that different regularization methods lead to different finite effective actions. We show that in this model dimensional regularization and regularization by dimensional reduction yield the same effective action. Consequently, the superfield approach preserves BRS invariance for this model.engjournal articlehttp://dx.doi.org/10.1016/S0550-3213(96)00671-2http://arxiv.org/abs/hep-th/9609074http://www.sciencedirect.com/scienceopen access53Topologically Massive GravityGauge-TheoriesDimensional RegularizationAlgebraic RenormalizationFinitenessReductionMatterFieldsShiftFísica (Física)22 Física
