Abstract
Building on earlier work on football-shaped extra dimensions, we construct a compact codimensiontwo
braneworld with precisely one brane. The two extra dimensions topologically represent a 2-torus
which is stabilized by a bulk cosmological constant and magnetic flux. The torus has positive constant
curvature almost everywhere, except for a single conical singularity at the location of the brane. In
contradistinction to the football-shaped case, there is no fine-tuning required for the brane tension. We
also present some plausibility arguments why the model should not suffer from serious stability issues.
