Improved vacuum stability in a 5D extra-dimension model

Year: 2012

Type: article

Abstract: In this paper we study the renormalization effects of the quark flavor mixings and the Higgs self-coupling in a five-dimensional model where the boson fields are propagating in the bulk while the matter fields are localized to the brane. We first explore the evolution behaviors for the Cabibbo-Kobayashi-Maskawa matrix in this scenario. Then, in light of the recent LHC bounds on the Higgs mass, we find that the Higgs self-coupling evolution has an improved vacuum stability condition, which is in contrast with that of Standard Model and the Universal Extra Dimension scenario, where the theory has a much lower ultraviolet cutoff.
