Asymptotic Freedom in Inflationary Cosmology with a Non-Minimally Coupled Higgs Field
Abstract
We consider the renormalization group improvement in the theory of the Standard Model Higgs boson playing the role of an inflaton with a strong non-minimal coupling to gravity. It suggests the range of the Higgs mass 124 < MH < 180 GeV compatible with the current CMB data. We find the phenomenon of asymptotic freedom induced by this non-minimal curvature coupling, which brings the theory to the weak coupling domain. The renormalization group running of a basic quantity - the anomalous scaling in the nonminimally coupled Standard Model, which analytically determines all characteristics of the CMB spectrum - brings it to small positive values at the inflation scale. This property also might underlie the formation of initial conditions for the inflationary dynamics in quantum cosmology.
