Abstract

We consider a quantum corrected inflation scenario driven by a generic GUT or Standard Model type particle model whose scalar field playing the role of an inflaton has a strong non-minimal coupling to gravity. We show that currently widely accepted bounds on the Higgs mass falsify the suggestion of the paper arXiv:0710.3755 (where the role of radiative corrections was underestimated) that the Standard Model Higgs boson can serve as the inflaton. However, if the Higgs mass could be raised to 230\sim 230 GeV, then the Standard Model could generate an inflationary scenario with the spectral index of the primordial perturbation spectrum ns0.935n_s\simeq 0.935 (barely matching present observational data) and the very low tensor-to-scalar perturbation ratio r0.0006r\simeq 0.0006.
