BPS states in AdS${}_3$ Supergravity with Chiral Torsion

Abstract

In this letter, we construct a supersymmetric model, obtained by deforming $\mathcal{N}=2$ AdS${}_3$ supergravity through a chiral vector component of the torsion. Moreover, we study the existence of BPS states of such theory, by inspecting the presence of Killing spinors on a specific bosonic solution.
