The D[subscript 2k] R[subscript 4] Invariants of N=8 Supergravity Accessed Terms of Use Detailed Terms

The existence of a linearized SUSY invariant for N = 8 supergravity whose gravitational components are usually called R was established long ago by on-shell superspace arguments. Superspace and string theory methods have also established analogous higher dimensional DR invariants. However, very little is known about the SUSY completions of these operators which involve other fields of the theory. In this paper we find the detailed component expansion of the linearized R invariant starting from the corresponding superamplitude which generates all component matrix elements of the operator. It is then quite straightforward to extend results to the entire set of DR operators.
