| Vienna Theory Lunch Club - Towards renormalizable models for gauge fields in non-commutative space |
| Speaker: | Daniel Blaschke (TU Wien) |
| Abstract: | When trying to construct a quantum field theory on non-commutative space-time, e.g. by employing the so-called Groenewold-Moyal star product, one inevitably runs into the infamous UV/IR mixing problem where new kinds of non-local IR divergences prevent the model from being renormalizable. In fact, so far only some modified scalar field theories on Euclidean non-commutative spaces have been found to be renormalizable by successfully circumventing problems due to UV/IR mixing. In this talk I give an introduction to this interesting field of research and present a promising candidate for a renormalizable non-commutative gauge theory.
