(Super)conformal many-body quantum mechanics with extended supersymmetry

TLDR: In this article, a conformal N=4 extension of AM−1 Calogero models is presented, which for generic values of the coupling constant are not SU(1, 1|2) superconformal.

Abstract: We study N=4 supersymmetric quantum-mechanical many-body systems with M bosonic and 4M fermionic degrees of freedom. We also investigate the further restrictions of conformal and superconformal invariance. In particular, we construct conformal N=4 extensions of the AM−1 Calogero models, which for generic values of the coupling constant are not SU(1,1|2) superconformal. This class of models is also extended to arbitrary (even) N. We give both Hamiltonian and (classical) Lagrangian formulations. In the latter case, we use both component and N=4 superfield formulations.
