Abstract
Abstract We show that the phase transition, obtained previously in reggeon field theory for α (0) > 1, is a consequence of a new kind of vacuum instability. The action of a field operator on the vacuum generates a disturbance that expands in space with a definite velocity towards a degenerate ground state. We show how the resulting J -plane singularities can be interpreted as a sum over a highly degenerate spectrum with a non-vanishing energy gap. The resulting picture of the phase transition stems from the pseudo-hermiticity of the reggeon field theory and is basically different from the spontaneous symmetry breaking.
