Non-perturbative gauge-Higgs unification: symmetries and order parameters

  title={Non-perturbative gauge-Higgs unification: symmetries and order parameters},
  author={Nikos Irges and Francesco Knechtli},

A bstractWe consider pure SU(N) gauge theories defined on an orbifold lattice, analogous to the S1/$ {{\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.

Symmetry and Z2-Orbifolding Approach in Five-Dimensional Lattice Gauge Theory

Difficulties for five-dimensional gauge-higgs unification.
For five-dimensional gauge theories where all fields propagate in the bulk and the fifth direction is compactified on the orbifold S1/Z2, it is shown that the assumption that the low-energy vector-boson spectrum consists of the W(+/-), Z, and gamma only, is inconsistent with the experimental requirements.
