Radion stabilization in the presence of Wilson line phase
arXiv:1404.5125 · doi:10.1093/ptep/ptu097
Abstract
We study the stabilization of an extra-dimensional radius in the presence of a Wilson line phase of an extra $U(1)$ gauge symmetry on a five-dimensional space-time, using the effective potential relating both the radion and the Wilson line phase at the one-loop level. We find that the radion can be stabilized by the introduction of a small number of fermions.
