Abstract and 1 Introduction

2 U(1) gauge theory on a warped background

3 Gauge-Higgs inflation on a warped background

4 Conclusions and discussions, Acknowledgements, and References

2 U(1) gauge theory on a warped background

2.1 Randall-Sundrum metric and action integral

The spacetime is assumed to be 5d one with the RS metric given by [8, 9]


2.2 Conjugate boundary conditions


where β is a constant called a twisted phase, the superscript C denotes a 4d charge conjugation, θC is a real number, and the asterisk means the complex conjugation. Then, the covariant derivatives obey the relations:


2.3 Mass spectrum


Then, the action integral is rewritten as




2.4 Effective potential

Let us derive the effective potential for the Wilson line phase θ(= θ(x)). Taking the standard procedure, a d-dimensional effective potential involving one degree of freedom at the one-loop level is given b

[3] We introduce both Mψ and cσ′ (y) in a general standpoint, and we will see that cσ′ (y) is forbidden by imposing specific boundary conditions on fields in the next subsection.
