Prepotential in 5d $\mathcal{N}=1$ with higher-derivative correction
The (bosonic part of the) action of five-dimensional $\mathcal{N}=1$ supergravity coupled to a number of vector multiplets reads
$$S=\frac{1}{2\kappa_5^2}\int\star(R-\frac{1}{2}h_{ij}(\phi)\partial-\...

How to construct the final action for a supergravity theory $N = 1$ in 4D?
I am trying to understand the basics of supergravity theory $N = 1$ in 4D, which combines supersymmetry and general relativity. I know that the theory involves a spin 2 field whose quantum is the ...

Is there a Lagrangian for Super-Gravity?
Einsteins field equations can be derived from the Einstein-Hilbert action which only involves the scalar curvature $R$ of the spacetime manifold. This is simply
$$S = \int_M R.$$
The volume form or ...

Gravitino Equation of motion in second-order formalism
In Freedman and Proeyen's text on supergravity they derive the equation of motion for the gravitino using the second order formalism. However, I'm not exactly clear as to how they use partial ...

New-minimal vs old-minimal supergravity
New-minimal set of supergravity auxiliary fields includes a two-form field, whereas the old-minimal auxiliary set includes a vector and a complex scalar. Is anyone aware of how to transform between ...

$D=10$ Type IIB Supergravity action
In this review of SUSY gauge theories and the $AdS-CFT$ correspondence, on Page-29, firstly the Supergravity action for $D = 11$ is written. The authors then say that the action for the Type IIA ...

Action with self-dual form field strength
It is said that writing down an action in presence of a self-dual field strength is subtle and not known till date (February 2016). The familiar example people give is that of type IIB super-gravity ...

Is it possible to derive the brane action in pure supergravity?
The branes that source the RR fields of supergravity are described by the DBI action plus a CS term. I know this only from superstring considerations.
Is there a way to find this result without ...

Derivation of the supergravity action in 11D
The Einstein-Hilbert action of general relativity is uniquely determined by general covariance and the requirement that only second derivatives in the metric appear. Yang-Mills theory can be motivated ...
