Abstract: (Elsevier)
The stability of the vacuum of the orbital dual model with zero intercept with respect to spurion emission is investigated. Although the model is not fully satisfactory because of the presence of negative norm states, it serves as a simplified laboratory for the more realistic (and more complicated) models. Feynman rules for the calculation of the effective potential are developed, and the problem of finding the Goldstone minimum is reduced to a non-linear integral equation. The propagator of the model is also determined, and trajectories are shown to remain linear.
