Superspace formulations of ten–dimensional supergravity
We present a new formulation for N = 1, D = 10 supergravity in superspace, in presence of a Lorentz Chern–Simons–form. This formulation entails the following properties: it furnishes a solution of the Bianchi identities that is algebraically consistent to all orders in α; at first order it is the simplest formulation proposed so far, and it is therefore most suitable for an explicit higher orde...
متن کاملA Superspace Approach to Branes and Supergravity*
Recent developments in string and M theory rely heavily on supersymmetry suggesting that a revival of superspace techniques in ten and eleven dimensions may be advantageous. Here we discuss three topics of current interest where superspace is already playing an important role and where an improved understanding of superspace might provide additional insight into the issues involved. *In Proceed...
متن کاملGauging of Flat Groups in Four Dimensional Supergravity
We show that N = 8 spontaneously broken supergravity in four dimensions obtained by Scherk–Schwarz generalized dimensional reduction can be obtained from a pure four dimensional perspective by gauging a suitable electric subgroup of E7,7. Owing to the fact that there are non isomorphic choices of maximal electric subgroups of the U-duality group their gaugings give rise to inequivalent theories...
متن کاملSupersymmetry, supergravity, superspace and BRST symmetry in a simple model
In these lectures we shall introduce rigid supersymmetry, supergravity (which is the gauge theory of supersymmetry) and superspace, and apply the results to BRST quantization. We assume that the reader has never studied these topics. For readers who want to read more about these “super” subjects, we give a few references at the end of this contribution, but the whole point of these lectures is ...
متن کاملSuperspace supergravity and supersymmetrization of R 4 Filipe Moura
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 e...
