An intriguing hypothesis is that gravity may be nonperturbatively renormalizable via the notion of asymptotic safety (AS). We show that the Higgs sector of the standard model (SM) minimally coupled to asymptotically safe gravity can generate the observed near scale-invariant spectrum of the Cosmic Microwave Background through the curvaton mechanism. The resulting primordial power spectrum places an upper bound (CMB) on the Higgs mass, which for finely tuned values of the curvaton parameters, is compatible with the recently released Large Hadron Collider (LHC) data.
