Flux-confinement in dilatonic cosmic strings

We study dilaton electrodynamics in flat spacetime and exhibit a set of global cosmic-string-like solutions in which the magnetic flux is confined. These solutions continue to exist for a small enough dilaton mass but cease to exist above a critical value depending on the magnetic flux. There also exist domain wall and Dirac monopole solutions. We discuss a mechanism whereby magnetic monopoles might have been confined by dilaton cosmic strings during an epoch in the early universe during which the dilaton was massless.
