Field Theory with Coordinate Dependent Noncommutativity
Daniel N. Blaschke, Francois Gieres, Stefan Hohenegger +2
We discuss the formulation of classical field theoretical models on -dimensional noncommutative space-time defined by a generic associative star product. A simple procedure for…
BPHZ renormalization and its application to non-commutative field theory
Daniel N. Blaschke, Francois Gieres, Franz Heindl +2
In a recent work a modified BPHZ scheme has been introduced and applied to one-loop Feynman graphs in non-commutative phi^4-theory. In the present paper, we first review the BPHZ m…
On the Renormalization of Non-Commutative Field Theories
Daniel N. Blaschke, Thomas Garschall, Francois Gieres +3
This paper addresses three topics concerning the quantization of non-commutative field theories (as defined in terms of the Moyal star product involving a constant tensor describin…
Degenerate noncommutativity
Harald Grosse, Michael Wohlgenannt
We study a renormalizable four dimensional model with two deformed quantized space directions. A one-loop renormalization is performed explicitly. The Euclidean model is connected…
Scalar field propagation in the phi^4 kappa-Minkowski model
S. Meljanac, A. Samsarov, J. Trampetic +1
In this article we use the noncommutative (NC) kappa-Minkowski phi^4 model based on the kappa-deformed star product, ({*}_h). The action is modified by expanding up to linear order…
Noncommutative kappa-Minkowski phi4 theory: Construction, properties and propagation
S. Meljanac, A. Samsarov, J. Trampetic +1
We have constructed noncommutative phi^4 field theory on kappa-Minkowski spacetime. Quantum properties via 2-point functions were analized, and effect of birefringence for the mass…
