“…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]). Generalizing these constructions to gauged ME and YME supergravities constitutes a major step toward establishing this proposal and has the potential for incorporating a large body of supergravity literature into the rapidly developing field of amplitude calculations.…”

Gauged Supergravities and Spontaneous Supersymmetry Breaking from the Double Copy Construction

et al. 2018

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.

“…Effective non-gravitational theories for which a double-copy construction is known include the Dirac-Born-Infeld and the special Galileon theories, as well as the nonlinear sigma model [38,39,40,41,42,43,44]. Double-copy structures have also been identified for various string-theory amplitudes, [45,46,47,48,49,50,51,52,53], within the Cachazo-He-Yuan formalism [54,55,56,57,58], in the context of ambitwistor string theories [59], and at the level of linearized supermultiplets [60,61,62,63,64].…”

Scattering amplitudes have the potential to provide new insights to the study of supergravity theories with gauged R-symmetry and Minkowski vacua. Such gaugings break supersymmetry spontaneously, either partly or completely. In this paper, we develop a framework for double-copy constructions of Abelian and non-Abelian gaugings of N = 8 supergravity with these properties. They are generally obtained as the double copy of a spontaneously-broken (possibly supersymmeric) gauge theory and a theory with explicitly-broken supersymmetry. We first identify purely-adjoint deformations of N = 4 super-Yang-Mills theory that preserve the duality between color and kinematics. A combination of Higgsing and orbifolding yields the needed duality-satisfying gauge-theory factors with multiple matter representations. We present three explicit examples. Two are Cremmer-Scherk-Schwarz gaugings with unbroken N = 6, 4 supersymmetry and U (1) gauge group. The third has unbroken N = 4 supersymmetry and SU (2)× U (1) gauge group. We also discuss examples in which the double-copy method gives theories with explicitly-broken supersymmetry.

“…The present record being at the four point five-loop level for maximal supergravity [15]. Moreover, an elaborate web of theories connected via color-kinematics duality exists that includes matter couplings and various numbers of supersymmetries [16][17][18]. All these results point towards the double copy being a generic property of gravity alluding at a hidden kinematical algebra which has resisted discovery so far.…”

Effective action of dilaton gravity as the classical double copy of Yang-Mills theory

We compute the classical effective action of color charges moving along worldlines by integrating out the Yang-Mills gauge field to next-to-leading order in the coupling. An adapted version of the Bern-Carrasco-Johansson (BCJ) double-copy construction known from quantum scattering amplitudes is then applied to the Feynman integrands, yielding the prediction for the classical effective action of point masses in dilaton gravity. We check the validity of the result by independently constructing the effective action in dilaton gravity employing field redefinitions and gauge choices that greatly simplify the perturbative construction. Complete agreement is found at next-to-leading order. Finally, upon performing the post-Newtonian expansion of our result, we find agreement with the corresponding action of scalar-tensor theories known from the literature. Our results represent a proof of concept for the classical double-copy construction of the gravitational effective action and provides another application of a BCJ-like double copy beyond scattering amplitudes.
