Consistent Construction of Perturbation Theory on Noncommutative Spaces
Stefan Denk, Volkmar Putz, Michael Wohlgenannt
We examine the effect of non-local deformations on the applicability of interaction point time ordered perturbation theory (IPTOPT) based on the free Hamiltonian of local theories.…

Towards UV Finite Quantum Field Theories from Non-Local Field Operators
Stefan Denk, Volkmar Putz, Manfred Schweda +1
A non-local toy model whose interaction consists of smeared, non-local field operators is presented. We work out the Feynman rules and propose a power counting formula for arbitrar…
