Noncommutative kappa-Minkowski phi4 theory: Construction, properties and propagation

Abstract

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 massive scalar field has been found.
