Hawking Radiation of Black Rings from Anomalies

Abstract

We derive Hawking radiation of 5-dimensional black rings from gauge and gravitational anomalies using the method proposed by Robinson and Wilczek. We find as in the black hole case, the problem could reduce to a (1+1) dimensional field theory and the anomalies result in correct Hawking temperature for neutral,dipole and charged black rings.Comment: 15 pages,Latex; revised version, typos corrected, reference added
