Static spin-32perturbations of a two-black-hole system

Abstract
We construct the most general static regular, nongauge spin-32 perturbations on the Majumdar-Papapetrou background for two black holes. The construction applies a limiting procedure by combining Killing spinors and spacetime perturbations. The supercharge associated with the spin-32 field is proportional to the difference of the mass parameters, implying that a system of two equal black holes has zero supercharge.
