Interacting scalar field theory in $κ$-Minkowski spacetime
Abstract
Description
We construct an complex scalar field theory in $κ$-Minkowksi spacetime, which respects $κ$-deformed Poincaré symmetry. One-loop calculation shows that the theory is finite and needs finite renormalization to be compatible with the $κ\to \infty$ limit. The loop result also has an imaginary valued correction due to the complex poles present in the propagator.
