Scientific paper

An alternate scheme of quantizing extended vacuum structures is further developed to include the case of scalar multiplets. Approximate static bubble and multibubble states are presented for several scalar theories which possess a symmetry that creates energetically degenerate minima for their potentials. The first theory is the standard ψ4 model, while the second theory is a model which exhibits spontaneous CP violation. The approximate bubble solution is consistent with selecting the particle spectrum associated with a constant vacuum expectation value for the scalar field. The spectrum of radiation associated with the collapse is calculated in lowest-order approximation and the average number of emitted particles is found to be proportional to the area of the bubble. Approximate multibubble solutions are presented and the energy of these configurations exhibits an attraction between the bubbles.
