On Entropy Function for Supersymmetric Black Rings | Rong-Gen Cai
; Da-Wei Pang
; | Date: |
6 Feb 2007 | Abstract: | The entropy of five-dimensional black rings, which are solutions of $U(1)^{3}$ minimal supergravity, is calculated via the entropy function formalism. We find that after dimensional reduction down to four-dimensional spacetime, where the near horizon geometry becomes $AdS_{2} imes S^{2}$, the entropy function works very well and gives the correct entropy. We also compute the higher order corrections due to the Gauss-Bonnet term. | Source: | arXiv, hep-th/0702040 | Services: | Forum | Review | PDF | Favorites |
