Hidden Symmetries in Black Holes

In this presentation we aim to discuss the existence of the so-called hidden conformal symmetries for the case of black rings doughnut shaped black hole solutions of General Relativity in five spacetime dimensions. Through the application of the monodromy technique to the massless Klein Gordon equation in the near horizon black ring regions, we compute the temperatures and central charges of the 2-dimensional conformal theory duals (2D-CFT) of the system. Similar results are obtained from the study of the Casimir operator for these geometries. Considering the recently proposed 2D-CFT duality for Kerr and 5D Myers-Perry black holes, we conjecture the general features required in the black hole solutions to exhibit a 2D conformal field duals.
