The Moyal product then contains a finite number of derivatives, which allows to avoid difficulties of the standard approach. As an example, we construct a two-dimensional noncommutative field theory model based on the Moyal product with a bifermionic parameter and show that it has a locally conserved energy-momentum tensor. The model has no problems with the canonical quantization and appears to be renormalizable.8 pages, v2: reference added, v3: misprints correctedHigh Energy Physics - TheorySpace-time noncommutativity with a bifermionic parametertext
