M-Theory N=1 Effective Supergravity in Four Dimensions

We present a general `off-shell' description of the effective N=1 supergravity describing the low-energy limit of M-theory compactified on (Calabi-Yau) x S1/Z2. In our formulation, the M-theory Bianchi identities are imposed by the equations of motion of four-dimensional supermultiplets. Modifications of these identities (resulting for instance from contributions localized at orbifold singularities or non-perturbative sources like five-branes) can then easily be implemented.

On the Effective N=1 Supergravity of M-Theory

In the low-energy limit, M-theory compactified on S1/Z2 is formulated in terms of Bianchi identities with sources localized at orbifold singularities and anomaly-cancelling counterterms to the Wilson effective Lagrangian. Compactifying to four dimensions on a Calabi-Yau space leads to N=1 local supersymmetry. We derive a formulation of the effective supergravity which explicitly relates four-dimensional supergravity multiplets and field equations with these fundamental M-theory aspects. This formulation proves convenient for the introduction in the effective supergravity of non-perturbative M-theory contributions. It also applies to the universal sector of generic compactifications with N=1 supersymmetry.
