The Standard Model of elementary particles is based on the existence of the Higgs particle, which is responsible for the electroweak symmetry breaking but has not been detected in experiments so far. The next large accelerator LHC might discover the Higgs and possibly indicate extensions of the Standard Model. Among these there are theories in which the Higgs is a relic of an unobserved extra dimension. We investigate the simplest of these models, a gauge theory in five dimensions, on the lattice. Peculiar orbifold boundary conditions are imposed in the extra dimension. We present simulation results for the mass spectrum of the theory.
