Localization of the 5D supergravity action and Euclidean saddles for the black hole index

D Cassani, A Ruipérez, E Turetta - Journal of High Energy Physics, 2024 - Springer
A bstract We investigate equivariant localization of the gravitational on-shell action in odd
dimensions, focusing on five-dimensional ungauged supergravity. We analyze the …

Supersymmetric index for small black holes

C Chowdhury, A Sen, P Shanmugapriya… - Journal of High Energy …, 2024 - Springer
A bstract Supersymmetric elementary string states in the compactified heterotic string theory
are described by small black holes that have zero area event horizon. In this paper we …

Supersymmetric Index for Half BPS Black Holes in N= 2 Supergravity with Higher Curvature Corrections

S Hegde, A Sen, P Shanmugapriya… - arXiv preprint arXiv …, 2024 - arxiv.org
We compute the supersymmetric index of half BPS black holes in N= 2 supergravity with
higher curvature corrections and show that the result agrees with the degeneracy of …
