Gauged supergravities and spontaneous SUSY breaking from the double copy

Authors: Marco Chiodaroli, Murat Gunaydin, Henrik Johansson and Radu Roiban  Preprint Number: UUITP-37/17 Supergravities with gauged R-symmetry and Minkowski vacua allow for spontaneous supersymmetry breaking and, as such, provide a framework for building supergravity models of phenomenogical relevance. In this letter we initiate the study of double-copy constructions for these supergravities. On general grounds we expect that their scattering amplitudes are described by a double copy of the type: (Higgsed gauge theory) ⊗ (gauge theory with broken SUSY). We present a simple realization in which the resulting supergravity has U(1)_R gauge symmetry, spontaneously-broken N = 2 supersymmetry, and massive gravitini. This is the first instance of a double-copy construction for a gauged supergravity and for a theory with spontaneously-broken supersymmetry. The construction extends in a straightforward manner to a large family of gauged Yang-Mills-Einstein supergravity theories with or without spontaneous gauge symmetry breaking.
