Quantum properties of $U(1)$-like gauge theory on $\kappa$-Minkowski

In the 5-dimensional twisted $U(1)$-like gauge theory on $\kappa$-Minkowski, the one-loop one-point (tadpole) function was computed in arXiv:2107.14462. This article summarizes the construction of such a gauge theory and discusses the non-vanishing of the tadpole.
