Four dimensional Script R4 superinvariants through gauge completion

We fully compute the Script N = 1 supersymmetrization of the fourth power of the Weyl tensor in d = 4 x-space with the auxiliary fields. In a previous paper, we showed that their elimination requires an infinite number of terms; we explicitely compute those terms to order κ4 (three loop). We also write, in superspace notation, all the possible Script N = 1 actions, in four dimensions, that contain pure Script R4 terms (with coupling constants). We explicitely write these actions in terms of the θ components of the chiral density epsilon and the supergravity superfields R,Gm,WABC. Using the method of gauge completion, we compute the necessary θ components which allow us to write these actions in x-space. We discuss under which circumstances can these extra Script R4 correction terms be reabsorbed in the pure supergravity action, and their relevance to the quantum supergravity/string theory effective actions.
