We study a simple five-dimensional extension of the Standard Model,
compactified on a flat line segment in which there propagate Higgs and gauge
bosons of the Standard Model. We impose a Dirichlet boundary condition on the
Higgs field to realize its vacuum expectation value. Since a flat
Nambu-Goldstone zero-mode of the bulk Higgs is eliminated by the Dirichlet
boundary condition, a superposition of the Higgs Kaluza-Klein modes play the
role of the Nambu-Goldstone boson except at the boundaries. We discuss
phenomenology of our model at the LHC, namely the top Yukawa deviation and the
production and decay of the physical Higgs field, as well as the constraints
from the electroweak precision measurements.Comment: 24 pages, 8 figures, title changed, phenomenological consequences
