Abstract
We obtain the complete superconformal symmetry transformations on the worldvolume of a D3-brane in an AdS 5 × S 5 background by using a coset superspace approach. We show that in the large R-limit we recover all supersymmetries present on the worldvolume of a D3-brane in a Minkowski background, in particular the Volkov-Akulov supersymmetry. We conclude with a proposal for a scheme to construct higher derivative invariants in D = 4, $$ \mathcal{N} $$ = 4 settings.
Highlights
It is still an open question if superconformal higher-derivative invariants in D = 4, N = 4 supergravity exist
We compared the worldvolume transformation rules of a D3-brane embedded in a Minkowski background with those of a D3-brane embedded in an AdS5 × S5 background
AdS5 × S5 background and the Volkov-Akulov symmetries related to the Minkowski background
Summary
We briefly recap the formalism of Cartan forms on coset superspaces [11,12,13,14]. We use this formalism to write down the superisometries of Minkowski superspace and AdS5 × S5 superspace. The Cartan 1-forms and the parameters Σ (defining the superisometries) are split as follows. The eμa form the vielbein of the bosonic space and eαα is the matrix introduced in the boson-fermion parametrization of the coset representative. In the subsections we will use equations (2.7) and (2.13) to write down the supervielbein and superisometries of the Minkowski and AdS5 × S5 background superspaces
