New branches of electrically charged Einstein-Yang-Mills-Higgs solutions

摘要

We consider dyons and electrically charged monopole-antimonopole pairs in Einstein-Yang-Mills-Higgs theory. In the presence of an electric charge, bifurcations arise and new branches of solutions appear. For large values of the electric charge, spherically symmetric dyons approach limiting solutions related to the Penney solution of Einstein-Maxwell-scalar theory.
