Abstract
We consider pure SU(N) gauge theories defined on an orbifold lattice, analogous to the S 1 / \( {{\mathbb{Z}}_2} \) gauge theory orbifolds of the continuum, which according to the perturbative analysis do not have a Higgs phase. Non-perturbatively the conclusion for N even is the opposite, namely that spontaneous symmetry breaking does take place and some of the gauge bosons become massive. We interpret this new, non-perturbative phenomenon both mathematically and physically.
