DILATONIC MONOPOLES AND “HAIRY” BLACK HOLES — •Betti Hartmann¹, Yves Brihaye², and Jutta Kunz³ — ¹Department of Mathematical Sciences, University of Durham, United Kingdom — ²Faculté des Sciences, Université de Mons-Hainaut, Belgium — ³Fachbereich Physik, Universität Oldenburg, Germany

We study gravitating monopoles and non-abelian black holes of SU(2) Einstein-Yang-Mills-Higgs theory coupled to a massless dilaton, which appears naturally in many unified theories, including string theory. The domain of existence of these solutions is bounded and decreases with increasing dilaton coupling strength. The critical solutions of this system are Einstein-Maxwell-dilaton solutions.
