摘要：Lattice simulations of five-dimensional gauge theories on an orbifold revealed that there is spontaneous
symmetry breaking. Some of the extra-dimensional components of the gauge field play
the role of a Higgs field and some of the four-dimensional components become massive gauge
bosons. The effect is confirmed by computing the Coleman-Weinberg potential with a cutoff. We
compare the results of this computation with the lattice data.
