TL;DR
This paper develops a topological two-dimensional dilaton supergravity model by gauging an extended super-Poincaré algebra, resulting in a non-local gravitino field theory with novel algebraic structures.
Contribution
It introduces a new topological dilaton supergravity model based on an extended super-Poincaré algebra derived from an unconventional contraction of super de Sitter algebra.
Findings
The model is topological and two-dimensional.
It features a non-local gravitino field.
The algebra includes additional fermionic and bosonic generators.
Abstract
We present a topological version of two dimensional dilaton supergravity. It is obtained by gauging an extension of the super-Poincar\'e algebra in two space-time dimensions. This algebra is obtained by an unconventional contraction of the super de Sitter algebra. Besides the generators of the super de Sitter algebra it has one more fermionic generator and two more bosonic generators one of them being a central charge. The gauging of this algebra is performed in the usual way. Unlike some proposals for a dilaton supergravity theory we obtain a model which is non-local in the gravitino field.
