Abstract: (APS)
Many of the useful features of supergravities, such as admitting supersymmetric bosonic backgrounds governed by first-order Bogomol’nyi–Prasad–Sommerfield equations, can be realized in a much broader setting by relaxing the requirement of closure of the superalgebra beyond the level of quadratic fermion terms. The resulting pseudo-supersymmetric theories can be defined in arbitrary spacetime dimensions. We focus here on the N=1 pseudo-supersymmetric extensions of the arbitrary-dimensional bosonic string action, which were constructed a few years ago. In this paper, we recast these in the language of double field theory. More precisely, we construct the action and the corresponding pseudo-supersymmetry transformation rules in terms of O(D)×O(D) covariant derivatives, and we discuss consistent truncations on manifolds with generalized G structure. We thereby obtain a natural generalization of the previously known results for N=1 supersymmetric double field theory in D=10 to arbitrary dimensions. As explicit examples, we discuss Minkowski×G vacuum solutions and their corresponding pseudo-supersymmetry. We also briefly discuss squashed group manifold solutions, including an example with a Lorentzian signature metric on the group manifold G.
