Exact solutions in R2 SUGRA
Abstract
This paper is devoted to showing that the bosonic sector of R2 supergravity in four dimensions, constructed with the F term, admits a variety of exact and analytic solutions which include pp and anti-de Sitter (AdS) waves, asymptotically flat and AdS black holes and wormholes, as well as product spacetimes. The existence of static black holes and wormholes implies that a combination involving the Ricci scalar plus the norm of the field strength of the auxiliary two-form Bμ ν must be a constant. We focus on this sector of the theory, which has two subsectors depending on whether such a combination vanishes.
