6 Oct 2009 | | Abstract: | We consider the renormalization group improvement in the theory of the
Standard Model (SM) Higgs boson playing the role of an inflaton with a strong
non-minimal coupling to gravity. It suggests the range of the Higgs mass $135.6
{
m GeV} lesssim M_Hlesssim 184.5 {
m GeV}$ entirely determined by the
lower WMAP bound on the CMB spectral index. We find the phenomenon of
asymptotic freedom induced by this non-minimal curvature coupling, which brings
the theory to the weak coupling domain. Asymptotic freedom fails at the
boundaries of this domain, which makes the SM phenomenology sensitive to the
current cosmological data and thus suggests future more precise CMB
measurements as a SM test complementary to the LHC program. | | Source: | arXiv, 0910.1041 | | Services: | Forum | Review | PDF | Favorites | |
