Kurzfassung englisch:
It was proposed by Ooguri et.al that black holes in 5 dimensional gravity are unstable to helical phases i.e. phases in which Euclidean symmetry is spontaneously broken into a smaller "helical" symmetry in presence of Chern-Simons (CS) terms. In particular, interesting relations were noticed between the critical limit of the CS coupling and the supersymmetric value of the CS coupling in that the black hole solutions in the N = 2 supergravity theory are just marginally stable in presence of CS terms. With this motivation and the question as to whether black holes in supergravity can ever be unstable, we look at the stability of the black hole solution in N = 2 supergravity in presence of higher derivative corrections with respect to the helical phase transition and look at the constraints imposed on the central charges of the dual N = 1 SCFT.
