Asymptotically and non-asymptotically flat static black rings in charged dilaton gravity
arXiv:hep-th/0507097
Abstract
We systematically derive the asymptotically flat five dimensional black rings in EMd gravity by using the sigma model structure of the dimensionally reduced field equations. New non-asymptotically flat EMd black ring solutions in five dimensions are also constructed and their physical properties are analyzed.
