Decay Channels for Double Extremal Black Holes in Four Dimensions
Original language description
We explore decay channels for charged black holes with vanishing temperature in N = 2 supersymmetric compactifications of string theory. If not protected by supersymmetry, such extremal black holes are expected to decay as a consequence of the weak gravity conjecture. We concentrate on double extremal, non-supersymmetric black holes for which the values of the scalar fields are constant throughout space-time, and explore decay channels for which decay into BPS and anti-BPS constituents is energetically favorable. We demonstrate the existence of decay channels at tree level for large families of double extremal black holes. For specific charges, we also find stable nonsupersymmetric black holes, suggesting recombination of (anti)-supersymmetric constituents to a non-supersymmetric object.
