Abstract
The nature of dark matter and the fundamental quantum structure of spacetime could be directly linked in the asymptotic-safety framework. A toy model for the visible Higgs-Yukawa sector of the Standard Model, coupled to a dark sector through a portal coupling, provides a very first example for a model that simultaneously i) could become asymptotically safe at non-vanishing portal coupling, ii) could feature a strongly enhanced predictive power with calculable values for all interactions and thereby iii) give rise to calculable relations between the masses of the dark particles, their self-interactions, and the portal coupling.

An effective field theory (EFT) is characterized by an infinite number of couplings and often features Landau poles in its Renormalization Group (RG) flow
There are indications that the Higgs portal coupling to a dark sector consisting of a single, uncharged dark scalar must vanish at the Planck scale in order to achieve asymptotic safety in the UV [19]
