Higgs Field as Weak Boson in five Dimensions

Abstract

We propose a five-dimensional standard model which regards the Higgs field as a weak boson associated with the fifth dimension. The kinetic term of the Higgs field is obtained from the fifth components of field strengths defined in five dimension. The coupling constant of the fermion fields and the Higgs field is only the weak coupling constant. However, since the vacuum expectation value depends on the fifth coordinate, we can explain the various mass spectrum of elementary particles.
