Abstract

In this paper, we derive the energy momentum tensor for the translation
invariant noncommutative Tanasa scalar field model. The Wilson regularization
procedure is used to improve this tensor and the local conservation property is
recovered. The same question is addressed in the case where the Moyal star
product is deformed including the tetrad fields. It provides with an extension
of the recent work [J. Phys. A: Math. Theor. 43 (2010) 155202], regarding the
computation and properties of the Noether currents to the renormalizable
models.
