HET Brown Bag Seminar | Higher-derivative Kerr-Sen black holes
Robert Saskowski (Tianjin University)
In this talk, I will discuss recent developments in the use of solution-generating techniques for computing higher-derivative corrections. In particular, I will show how to use an O(2,1) boost to obtain the four-derivative corrections to the Kerr-Sen solution for two choices of higher-derivative action. The resulting solution, much like the case for Kerr, is perturbative in the spin parameter, but I will show how to get the exact thermodynamics and discuss a
conjectural BPS limit. Time allowing, I will also discuss ongoing work on the extremal non-supersymmetric Kerr-Sen black hole.
