Abstract

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 an extra dimension and thus possess horizon topology S^2 x R. We find that several branches of solutions exist. In addition, we determine the domain of existence of the non-abelian black strings.
