Parametrization of cosets for AdS5xS5 superstring action

TL;DR

This paper demonstrates that a recent alternative formulation of the AdS5xS5 superstring's superspace geometry is a specific parametrization of the standard coset, enabling the use of conventional methods.

Contribution

It clarifies the relationship between a new parametrization and the standard coset, facilitating the application of established techniques to the superstring model.

Findings

The new formulation is a particular parametrization of the standard coset.

Standard methods can be applied using this parametrization.

Simplifies the analysis of the superstring on AdS5xS5.

Abstract

A formulation recently proposed [arXiv:1506.07706] as an alternative to the usual coset PSU(2,2|4)/USp(2,2)USp(4) for the superspace geometry of the Type IIB superstring on an AdS5xS5 background is shown to be a particular parametrization of this coset. Standard methods can then be applied.
