Classical and Quantum Gravity 25(9): 095007.1361-63820264-9381http://nrs.harvard.edu/urn-3:HUL.InstRepos:7349762We study non-supersymmetric, extremal 4 dimensional black holes which arise upon compactification of type II superstrings on Calabi-Yau threefolds. We propose a generalization of the OSV conjecture for higher derivative corrections to the non-supersymmetric black hole entropy, in terms of the one parameter refinement of topological string introduced by Nekrasov. We also study the attractor mechanism for non-supersymmetric black holes and show how the inverse problem of fixing charges in terms of the attractor value of CY moduli can be explicitly solved.en-USJournal Article2012-01-0910.1088/0264-9381/25/9/095007
