Field theory amplitudes in a space with SU(2) fuzziness

Abstract:

The structure of field theory transition amplitudes in a three dimensional space whose spatial coordinates are noncommutative and satisfy SU(2) Lie algebra commutation relations is examined. In particular, the basic notions for constructing the observables of the theory as well as subtleties related to the proper treatment of δ-distributions are introduced. Explicit examples are given for scalar field theory amplitudes to lowest order of pertubation.
