• Popis: We study partial supersymmetry breaking from N = 2 to N = 1 by adding non-linear terms to the N = 2 supersymmetry transformations. By exploiting the necessary existence of a deformed supersymmetry algebra for partial breaking to occur, we systematically use N = 2 projective superspace with central charges to provide a streamlined setup. For deformed O(2) and O(4) hypermultiplets, besides reproducing known results, we describe new models exhibiting partial supersymmetry breaking with and without higher-derivative interactions.
