Contribution

It introduces a higher-dimensional SUSY gauge theory framework where the Higgs and inflaton are unified, and demonstrates its consistency with observed inflation parameters.

Findings

Unification of Higgs and inflaton in higher-dimensional gauge theory.

Successful explanation of inflation parameters without fine-tuning.

Potential for natural Higgs-inflaton unification in SUSY models.

Abstract

We study the possibility that the Higgs and the inflaton are the same single field or cousins arising from the extra space components of some higher-dimensional gauge field. We take 5D supersymmetric gauge theory with a matter compactified on S^1 as a toy model and evaluate the one-loop contribution to the Higgs-inflaton potential. Our gauge-Higgs-inflaton unification picture applied to the gauge field of intermediate energy scale (\sim 10^{13} GeV) can explain the observed inflation parameters without fine-tuning.
