Dyons with axial symmetry — •Betti Hartmann1, Burkhard Kleihaus2, and Jutta Kunz1 — 1FB8-Physik,Carl-von-Ossietzky Universität Oldenburg — 2Department of Mathematical Physics, University College Dublin,Irland
We construct axially symmetric dyons in SU(2) Yang-Mills-Higgs theory carrying topological charge n>1. In the Prasad-Sommerfield limit solutions with electric charge are obtained from purely magnetically charged solutions by simple scaling relations. For finite Higgs self-coupling λ, the solutions are constructed numerically and we find, that there exist n- and λ-dependent upper bounds for the electric charge of dyon solutions, beyond which localized solutions cease to exist. hep-th/0004108, Mod.
