Perturbed N=(2,2) supersymmetric sigma models on Lie groups    [PDF]

M. Ebrahimia, A. Rezaei-Aghdam

We have perturbed N=(2,2) supersymmetric WZW and sigma models on Lie groups by adding a term to their actions. Then, by using non-coordinate basis we have obtained conditions, from the algebraic point of view, under which the N=(2,2) supersymmetry is preserved. By applying this method, we have obtained conditions on the existence of N=(2,2) supersymmetry on the Drinfeld action (master action for the Poisson-Lie T dual sigma models).
