Boson stars in SU(2) Yang-Mills-scalar field theories
Yves Brihaye, Betti Hartmann, Eugen Radu
We present new spherically symmetric solutions of an SU(2) Einstein-Yang-Mills model coupled to a doublet of scalar fields. Sequences of asymptotically flat, Yang-Mills-boson star-…
Non-abelian black strings
Betti Hartmann
Non-abelian black strings in a 5-dimensional Einstein-Yang-Mills model are considered. The solutions are spherically symmetric non-abelian black holes in 4 dimensions extended into…
Gravity localisation in a 6-dimensional brane world
Betti Hartmann, Yves Brihaye
We study a 6-dimensional Einstein-Born-Infeld-Higgs model. In the limit of infinite Born-Infeld coupling, this model reduces to an Einstein-Abelian-Higgs model, in which gravity lo…
Static solutions of a 6-dimensional Einstein-Yang-Mills model
Yves Brihaye, Fabien Clement, Betti Hartmann
We study the Einstein-Yang-Mills equations in a 6-dimensional space-time. We make a self-consistent static, spherically symmetric ansatz for the gauge fields and the metric. The me…
Spherically symmetric solutions of a (4+n)-dimensional Einstein-Yang-Mills model with cosmological constant
Yves Brihaye, Betti Hartmann
We construct solutions of an Einstein-Yang-Mills system including a cosmological constant in 4+n space-time dimensions, where the n-dimensional manifold associated with the extra d…
Spherically symmetric Yang-Mills solutions in a (4+n)- dimensional space-time
Yves Brihaye, Fabien Clement, Betti Hartmann
We consider the Einstein-Yang-Mills Lagrangian in a (4+n)-dimensional space-time. Assuming the matter and metric fields to be independent of the n extra coordinates, a spherical sy…
