Abstract
Abstract: For the five dimensional N = 2 black rings, we study the supersymmetry enhancement and identify the global supergroup of the near horizon geometry. We show that the global part of the supergroup is OSp(4 ∗ |2) × SL(2) which is the same as the small black string. We show that results obtained by applying the entropy function formalism and the c-extremization approach to the black ring solution are in agreement with the microscopic entropy calculation. Also, we extend our calculation to the small black ring solution and compute the modification of the corresponding parameters.
