Degenerate noncommutativity

arXiv:1201.5982 · doi:10.1140/epjc/s10052-012-2153-4

Abstract

We study a renormalizable four dimensional model with two deformed quantized space directions. A one-loop renormalization is performed explicitly. The Euclidean model is connected to the Minkowski version via an analytic continuation. At a special value of the parameters a nontrivial fixed point of the renormalization group occurs.
