  • Higgs inflation, seesaw physics and fermion dark matter 
    Okada, Nobuchika; Shafi, Qaisar (Elsevier Science BV, 2015-06-03)
    We present an inflationary model in which the Standard Model Higgs doublet field with non-minimal coupling to gravity drives inflation, and the effective Higgs potential is stabilized by new physics which includes a dark ...
  • Non-minimal quartic inflation in supersymmetric SO(10) 
    Leontaris, George K.; Okada, Nobuchika; Shafi, Qaisar (Elsevier Science, 2016-12-16)
    We describe how quartic (λφ4) inflation with non-minimal coupling to gravity is realized in realistic supersymmetric SO(10)models. In a well-motivated example the 16 −16Higgs multiplets, which break SO(10)to SU(5)and yield ...
