Stabilizing Dark Matter with Quantum Scale Symmetry: Executive Summary

In these proceedings, we report on a secluding mechanism for dark matter from quantum scale symmetry: in the presence of an asymptotically safe ultraviolet fixed point at trans-Planckian scales, the renormalization group flow of the gauge–Yukawa couplings can control dark matter decays, without the need for discrete or global symmetries. We show explicitly how the mechanism works for an SU(6) model and indirectly constrain physical mass scales of the theory. Abstract Published by the Jagiellonian University 2026 authors
