Partial $\mathcal{N}=2$ Supersymmetry Breaking and Deformed Hypermultiplets

Abstract

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