Restricted Supergauge invariance, N=2 Coadjoint Orbit and N=2 Quantum Supergravity

TL;DR

This paper demonstrates that N=2 superconformal transformations can be viewed as restricted N=1 supergauge transformations within a supergauge theory, leading to a derivation of the Osp(2,2) current algebra in N=2 supergravity.

Contribution

It introduces a novel perspective by relating N=2 superconformal transformations to restricted N=1 supergauge transformations and derives the Osp(2,2) current algebra in this framework.

Findings

N=2 superconformal transformations are equivalent to restricted N=1 supergauge transformations.

A canonical derivation of the Osp(2,2) current algebra is achieved.

The approach provides new insights into N=2 supergravity structure.

Abstract

It is shown that the N=2 superconformal transformations are restricted N=1 supergauge transformations of a supergauge theory with Osp(2,2) as a gauge group. Based on this result, a canonical derivation of the Osp(2,2) current algebra in the superchiral gauge formulation of N=2 supergravity is presented.
