ResumoSymmetry breaking is studied systematically in a multi-Regge resonance production model. Consistency of the planar bootstrap with broken symmetry requires ideal nonets to have equal spacing between ϱ, K∗ and φ trajectories. Non-planar diagrams generate a leading vacuum singularity near one. Formulae relating symmetry breaking of the pomeron couplings and of produced particle multiplicities are given.
