Superspace supergravity and supersymmetrization of R 4 Filipe Moura

چکیده
We briefly review how to obtain N = 1, 2 Poincaré supergravity theories in four dimensions from the corresponding conformal theories. We then present our recent works on the supersymmetrization of their leading string correction. We show that, in the ”old minimal” formulations of these theories, when going on-shell the auxiliary fields which come from multiplets with physical fields cannot be eliminated, but those ones that come from compensating multiplets without any physical fields can be eliminated. We conjecture similar results for other versions of these theories.

Four Dimensional " Old Minimal " N = 2 Supersymmetrization of R 4
We write in superspace the lagrangian containing the fourth power of the Weyl tensor in the " old minimal " d = 4, N = 2 supergravity, without local SO(2) symmetry. Using gauge completion, we analyze the lagrangian in components. We find out that the auxiliary fields which belong to the Weyl and compensating vector multiplets have derivative terms and therefore cannot be eliminated on-shell. On...
متن کاملR 4 terms and d = 4 supergravity
We start by a concise yet thorough revision of four-dimensional super-space supergravity. We present curved superspace geometry, for arbitrary N , including torsion, curvature and Bianchi identities. We motivate the choice of torsion constraints. We then consider the particular cases of N = 1, 2. In both cases we show how Poincaré supergravity can be obtained from conformal supergravity. We see...
متن کاملFour dimensional supersymmetrization of R 4 1 Filipe Moura
We review our recent works on the supersymmetrization of the leading string correction (the R term) to N = 1, 2 supergravity theories in four dimensions. We show that, in the ”old minimal” formulations of these theories, when going on-shell in the presence of this correction, the auxiliary fields which come from multiplets with physical fields cannot be eliminated, but those ones that come from...
متن کاملFour dimensional N = 1 supersymmetrization of R 4 in superspace
We write an action, in four dimensional N = 1 curved superspace, which contains a pure R term with a coupling constant. Starting from the offshell solution of the Bianchi identities, we compute the on-shell torsions and curvatures with this term. We show that their complete solution includes, for some of them, an infinite series in the R coupling constant, which can only be computed iteratively...
متن کاملFour dimensional R4 superinvariants through gauge completion
We fully compute the 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 κ (three loop). We also write, in superspace notation, all the possible N = 1 actions, in four dimensions, that contain pure R term...
