Saddle point inflation in string-inspired theory

Year: 2015

Type: article

Abstract: The observed value of the Higgs mass indicates the possibility that there is no supersymmetry below the Planck scale and that the Higgs can play the role of the inflaton. We examine the general structure of saddle point inflation in string-inspired theory without supersymmetry. We point out that the string scale is fixed to be around the GUT scale |${\sim }10^{16}\,{\rm GeV}$| in order to realize successful inflation. We find that the inflaton can be naturally identified with the Higgs field.
