Orbifold Breaking of 3-3-1 Model
  We study the five dimensional SU(3)_c \times SU(3)_L \times U(1)_X gauge theory (3-3-1 Model) in which the gauge symmetry is broken down through orbifold compactification to four dimensions. The new model has several distinguishing features compared to the usual four dimensional model. We develop the formalism, and give expressions for the gauge boson masses, mixings and their couplings to the fermions. Phenomenology of the model is briefly studied.
