Feynman amplitudes in renormalizable non-commutative quantum field theory

Abstract:

We consider here the Feynman amplitudes of renormalizable non-commutative quantum field theory models. Different representations (the parametric and the Mellin one) are presented. The latter further allows the proof of meromorphy of a amplitude in the space-time dimension. This paves the road for the dimensional renormalization of these theories.
