A double copy for N=2{\cal N}=2 supergravity: a linearised tale told on-shell

preprint2016arXivOpen access

Abstract

We construct the on-shell double copy for linearised four-dimensional N=2{\cal N}=2 supergravity coupled to one vector multiplet with a quadratic prepotential. We apply this dictionary to the weak-field approximation of dyonic BPS black holes in this theory.
