“…[10,11]. The double copy applies to tree-and loop-level amplitudes [12][13][14], as well as classical solutions [15][16][17], and extends earlier string-theory results [18]. Recent success in reformulating large families of Maxwell-Einstein (ME) [19][20][21][22][23] and Yang-Mills-Einstein (YME) supergravities [24][25][26] in the double copy language has prompted the proposal that all theories of gravity could be regarded as double copies of some sort [22] (see also [27]).…”

Gauged Supergravities and Spontaneous Supersymmetry Breaking from the Double Copy Construction

Supergravities with gauged R symmetry and Minkowski vacua allow for spontaneous supersymmetry breaking and, as such, provide a framework for building supergravity models of phenomenological relevance. In this Letter, we initiate the study of double copy constructions for these supergravities. We argue that, on general grounds, we expect their scattering amplitudes to be described by a double copy of the type (spontaneously broken gauge theory)⊗ (gauge theory with broken supersymmetry). We present a simple realization in which the resulting supergravity has Uð1Þ R gauge symmetry, spontaneously broken N ¼ 2 supersymmetry, and massive gravitini. This is the first instance of a double copy construction of a gauged supergravity and of 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.

“…While only proven at tree-level for pure gauge theory [60], this conjecture can be applied to both massless and massive states [61,62] and has a wealth of non-trivial supporting evidence [63][64][65]. It raises the provocative question of whether exact solutions in general relativity satisfy similar simple relationships to their classical Yang-Mills counterparts, coined the classical double copy [66][67][68][69][70][71][72][73][74][75][76][77][78][79][80]. Such a relationship has indeed been found in the gravitational radiation emitted by spinning sources at 1PM order [81,82].…”

We develop a general formalism for computing classical observables for relativistic scattering of spinning particles, directly from on-shell amplitudes. We then apply this formalism to minimally coupled Einstein-gravity amplitudes for the scattering of massive spin 1/2 and spin 1 particles with a massive scalar, constructed using the double copy. In doing so we reproduce recent results at first post-Minkowskian order for the scattering of spinning black holes, through quadrupolar order in the spin-multipole expansion.

“…This question was first raised by the work of [8][9][10] in the context of Kerr-Schild solutions to the Einstein field equations. The Kerr-Schild double copy was further developed to more general geometries [11,12], gravitational wave backgrounds [13], and other applications [? ].…”

We extend Shen's recent formulation (arXiv:1806.07388) of the classical double copy, based on explicit color-kinematic duality, to the case of finite-size sources with non-zero spin. For the case of spinning Yang-Mills sources, the most general consistent double copy consists of gravitating objects which carry pairs of spin degrees of freedom. We find that the couplings of such objects to background fields match those of a classical (i.e. heavy) closed bosonic string, suggesting a string theory interpretation of sources related by color-kinematics duality. As a special case, we identify a limit, corresponding to unoriented strings, in which the 2-form Kalb-Ramond axion field decouples from the gravitational side of the double copy. Finally, we apply the classical double copy to extended objects, described by the addition of finite-size operators to the worldline effective theory. We find that consistency of the color-to-kinematics map requires that the Wilson coefficients of tidal operators obey certain relations, indicating that the extended gravitating objects generated by the double copy of Yang-Mills are not completely generic.
