Supersymmetric Calogero models from superfield gauging

Using the superfield gauging procedure, we construct new $\mathcal{N}=2$ and $\mathcal{N}=4$ superfield systems that generalize Calogero models. In the bosonic limit, these systems yield rational Calogero models and hyperbolic Calogero-Sutherland models in the $\mathcal{N}=2$ case, and their ${\rm U}(2)$spingeneralizationinthe${\cal N},{=},4$ case.
