摘要：We present a construction of non–Abelian gauge theories on the R4 ×S1/Z2 orbifold. We show
that no divergent boundary mass term for the Higgs field, identified with some of the fifth dimensional
components of the gauge field, is generated. The formulation of the theories on the lattice
requires only Dirichlet boundary conditions that specify the breaking of the gauge group. The
first simulations in order to resolve the issue whether these theories can be used at low energy
as weakly interacting effective theories have been performed. In case of a positive answer, these
theories could provide us with a new framework for studying electroweak symmetry breaking.
