The model contains a spurion tensor field that is responsible for the noncommutative structure of the model. Under double-dimensional reduction the model reduces to the exotic nonrelativistic particle in 2+1 dimensions.6 p.application/pdfeng(c) The American Physical Society, 2007Teoria de camps (Física)Relativitat (Física)Field theory (Physics)Relativity (Physics)info:eu-repo/semantics/article558225info:eu-repo/semantics/openAccess
