Lorentz symmetry breaking in the noncommutative Wess-Zumino model : one loop corrections

By Alysson Fábio Ferrari, Marcelo Gomes and Horacio Oscar Girotti


In this paper we deal with the issue of Lorentz symmetry breaking in quantum field theories formulated in a noncommutative space-time. We show that, unlike in some recent analysis of quantum gravity effects, supersymmetry does not protect the theory from the large Lorentz-violating effects arising from the loop corrections. We take advantage of the noncommutative Wess-Zumino model to illustrate this point
