  title={Time-ordered perturbation theory on noncommutative spacetime : basic rules},
  author={Yi Ting Liao and Klaus Sibold},
Assuming the S-matrix on noncommutative (NC) spacetime can still be developped perturbatively in terms of the time-ordered exponential of the interaction Lagrangian, we investigate the perturbation theory of NC field theory. We first work out with care some typical Green functions starting from the usual concepts of time-ordering and commutation relations for free fields. The results are found to be very different from those in the naive approach pursued in the literature. A simple framework… CONTINUE READING
