Higgs Boson in RG running Inflationary Cosmology

TL;DR

This paper proposes that the Higgs field, when coupled with asymptotically safe gravity, can produce the observed cosmic microwave background spectrum and constrains the Higgs mass based on cosmological data.

Contribution

It introduces a novel model linking Higgs physics with asymptotic safety in gravity to explain inflation and CMB observations.

Findings

Higgs field can generate near scale-invariant spectrum via curvaton mechanism

Upper bound on Higgs mass consistent with LHC data

Compatibility of Higgs-inflation model with cosmological observations

Abstract

An intriguing hypothesis is that gravity may be non-perturbatively renormalizable via the notion of asymptotic safety. We show that the Higgs sector of the 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 on the Higgs mass, which for finely tuned values of the curvaton parameters, is compatible with the recently released Large Hadron Collider data.
