Perturbation analysis of deformed Qballs and primordial magnetic field
Abstract
We study the excited states of Qballs by performing stationary perturbation on spherical Qballs. We find the exact solution of the stationary perturbation of the global Qball with the thin wall approximation. For local Qballs we solve the equations of motion for the perturbative part approximately by using expansion about the coupling constant. Furthermore we comment on the magnetic field generated by the excited Qballs during the phase transition precipitated by solitosynthesis and give the implications to cosmology.
